Picture Resolution 300 DPI [Why It Matters]

Jim Carrighan — November 19, 2018

If you search google or if you ask someone about how much resolution you should use in your images, almost every answer will be 300 DPI. However, is 300 DPI the right number? Shouldn’t it depend on the type of your image, if it has a lot of details, a lot of colors, among other factors?

Before we can say that 300 DPI is the right picture resolution or the wrong one, it is important that you understand what DPI is.

Simple way to convert inches to pixels.

Simply put, DPI is short for Dots Per Inch. DPI refers to the number of dots that are printed per inch. So, as you can easily see, the higher the DPI value that you have, the higher the resolution of the picture, and the less pixelated it will be.

Then, you need to think about the picture that you are printing. In case you are doing a logo, for example, you need to ensure that you have a minimum DPI so that you can have a good printed logo.

Another factor that you need to take into consideration is the colors. After all, colors are a very important part of any picture. In order to help you get the best pictures independently of the resolution be 300 DPI or any other, you want to make sure that you use CMYK and not RGB for your pictures.

But is a 300 DPI resolution the right one?

The truth is that as you already know, the higher the DPI the increased details you will get. So, by knowing this, you shouldn’t have any more problems. However, this is where you got it all wrong. Just take a look at a very common situation that continues to occur every day.

But what is pixel?

Let’s say that you have your client asked you for a photo with 300 DPI and they want to have it print out at 5” x 7”. So, you edited the beautiful image for your client and your digital image is showing very well at the 2018 X 1536 size. You send it back to your client and you consider that your job is done and that your client will be extremely happy with the result.

DPI vs PPI – hat is the difference?

Well, the client is really happy as soon as he opens the digital image. However, as soon as he opens it, he notices that the DPI is set at 72 and not at 300 DPI. So, since he loved your work, he just changes the DPI number from 72 to 300. While it doesn’t seem he is doing something wrong, the truth is that your client is enlarging your image more than 4 times. So, as a result, he will end up with an image with 8533 X 6400 size. So, as soon as he asks for the image to be printed out, they will tell him that this image will be completely blurry. So, he ends up with a blurry image. However, the worst thing is that he already had the perfect image to be printed out even if it was with a 72 DPI resolution and not with a 300 DPI resolution. The main point is that you have a good DPI set for the print size image that you want and it really doesn’t need to be 300 DPI.

What Is Pixel?

Jim Carrighan — November 19, 2018

While we have all heard about pixels, what is pixel? The truth is that if you ask this question to most people, they won’t be able to give you a straight answer. So, we decided, in this post, to answer the question what is pixel.

The term pixel comes from Picture Element (PEL). Simply put, a pixel is the smallest part or portion of a display or of an image that a computer is able to display or to print.

Check out how to convert inches to pixels easily.

In case you are someone who prefers to see an image that to read an explanation, then you just need to look at an image on your computer, for example. Zoom in and you will be able to see tiny squares. These tiny squares are called pixels. In case you take a look at a print image, you will also be able to see these little blocks. However, in this case, they are called DPI (Dots Per Inch).

A pixel can either be a square or round and pixels are usually arranged in a grid with two dimensions. So, as it is easy to understand now, the more pixels an image has, the more it will be close to the original image.

DPI vs PPI – discover the differences.

Resolution Of An Image

The total number of pixels that an image has is, in most cases, called the resolution of the image. However, this isn’t exactly how this term should be applied. The truth is that when you want to determine the number of pixels that an image has, you can express it through the resolution by using the width and the height. For example, in the case of a monitor, some have a 1280 X 1024 resolution. By looking at this resolution, you can easily say that this specific monitor has 1280 pixels when you’re counting horizontally and 1024 pixels when counting vertically.

Discover everything you need to know about pixel density.

However, this is not the only way that you have to show the number of pixels. Let’s take a camera, for example. Let’s say that you have a 5-megapixel camera. So, if you take the same formula we used before, and multiply the width by the height of the image, this would give you a total amount of 5 million pixels. So, looking back at our previous example, and multiply the width by the height, we would have 1280 X 1024 = 1,310,720, which is the same of saying that it has 1.31 megapixels.

Now that you already know what is pixel and that you can find the resolution in different ways, it is important that you know how many pixels you actually need in an image.

Simply put, the image resolution refers to the amount of detail that an image has. And this is why we mentioned the resolution before. This term can be applied not only to digital images but also to prints and even film images. Ultimately, the higher the resolution the image has, the more detailed the image is.

In case you are looking to buy a new camera, you will be able to see that most manufacturers try to sell you the cameras by only looking at the megapixels. However, you should take into consideration a lot more factors. After all, the truth is that most cameras on the market are a great option for a non-professional photographer. However, we are only looking at the megapixels. Since you need to look at other factors, there isn’t a specific number of megapixels that we can say for sure that a camera will work for you. The truth is that it really depends on what you want to do with the image, if you are considering printing it, enlarging it, among others.

DPI Vs PPI [Difference Explained]

Jim Carrighan — November 19, 2018

There is no question that digital imaging came to stay. After all, who can forget about Instagram or Pinterest, two of the biggest social networks that only work with images?

However, in what concerns digital image, there are still many questions. And one of the main ones is DPI vs PPI. So, in this article, we decided to show you once and for all the difference between DPI (Dots Per Inch) and PPI (Pixels Per Inch). Hopefully, when you finish reading this article, you won’t ever have this question popping up into your head when you are dealing with digital images.

Are you confused about converting pixels to inches and vice-versa?

One of the main reasons for the confusion of DPI vs PPI is related to the fact that DPI is actually an old terminology that kept being used in many different things. For example, there are people talking about DPI when they want to talk about the size of the image or when they want to mention its resolution.

However, in the last years, another terminology started to be used – the PPI or Pixels Per Inch. And this brought even more confusion.

So, let’s see exactly how DPI and PPI should be used and what are the main differences between DPI vs PPI.

Discover everything you need to know about pixel density.

#1: DPI (Dots Per Inch):

In what concerns DPI, this terminology should only be used for printers.

One of the things that you may not know is that each and every pixel output is made up of different inks, usually 4 to 6 colors. (More recent printers can use more colors.) So, when you want to print an image, these inks need to be mixed so that they can create all the different colors that you have on your image. So, basically, your image will be composed of a wide variety of tiny dots.

Usually, the higher the DPI, the better the colors will be displayed. This is why you take more time to print an image that has a lot of colors and details than a simpler image. Besides, the printer will also use more ink.

#2: PPI (Pixels Per Inch):

The PPI is a very simple measurement. The truth is that it simply refers to the number of pixels per image that your image has. So, as you can image, the PPI has a strong influence on the print size as well as on the quality of the output.

Let’s say that you have a low PPI. In this case, your image has few pixels per inch which will result in wider and bigger pixels. So, you will get a blurry or pixelated image.

While you will be reading that a specific PPI number is the best one, the truth is that the best PPI depends on the size of the print that you want.

Simple example of converting centimeters in pixels.

#3: DPI Vs PPI:

So, in order to completely understand the difference between DPI and PPI, there is nothing better than a simple example.

Let’s say that you need to print an image that has 300 PPI and that your printer has 1200 DPI. So, how much ink is in each pixel?

(1200 DPI X 1200 DPI) / (300 PPI X 300 PPI) = 16

So, you can easily say that each pixel will include 16 small ink dots.

In case you had a lower DPI, you would have fewer ink dots to fill in the same pixel. So, your colors and ultimate result would be worse. On the other side, if you had a larger DPI, this would mean that you would have more ink dots per pixel. So, as a result, you would have more accurate colors.

What You Need To Know About Pixel Density

Jim Carrighan — November 19, 2018

When you are talking about digital images, screens, monitors or even cameras, it is common to mention pixel density. But what exactly is pixel density?

Simply put, pixel density is what clearly describes the clarity and the sharpness. In other words, pixel density is the number of pixels that a specific display has. Traditionally, the pixel density is measured in PPI (Pixels Per Inch). So, you can say that the higher the pixel density, the higher it is the clarity and sharpness of the display. However, some people prefer to measure the pixel density in PPCM (pixels Per Centimeter).

Discover how to convert inches to pixels and vice-versa.

One of the things that you need to know about pixel density is that usually, vertical and horizontal density are the same since most displays have square pixels. However, there are some specific displays that can have non-square pixels.

So, how can you tell the pixel density of a specific display?

When you want to discover the pixel density of a specific display, you can use a simple formula:

Pixel Density= √[(Horizontal Number of Pixel^2) + (Vertical Number of Pixel^2)] / Screen Size

What is DPI in printing?

Does The Size Of The Screen Matter?

If you like to see the new trends in terms of computers, laptops, tablets, smartphones and even TVs, you probably already noticed that we have, on the market, the two extremes: the extremely large displays that can be hard to use on a daily basis, and those tiny displays. So, should you expect to have a lower pixel density on a small display than on a larger one?

The answer to this question isn’t unanimous since it depends on the displays. Nevertheless, you need to know that just because you are using a smaller display, this doesn’t mean that you have a lower pixel density than if you were using the larger display in the world.

Discover how to read an inches to pixels conversion chart.

So, let’s make a simple comparison of two different displays:

#1: A 32 inches Full-HD TV:

Let’s say that you have a 32 inches full HD TV at home and that you know it has a resolution of 1080p. This means that the screen displays the content at 1920 X 1080 pixels.

So, by applying the formula we showed above, the pixel density of this full HD TV is:

Pixel Density = √[ (1920^2) + (1080^2) ] / 32 = 68.84 PPI

How can you convert 3.5 cm in pixels?

#2: iPhone 7:

The iPhone 7 has a resolution of 1334 X 750 pixels. In addition, we know that the screen measures 4.7 inches.

So, by applying the formula of pixel density we mentioned above, the pixel density of the iPhone 7 is:

Pixel Density = √[ (1334^2) + (750^2) ] / 4.7 = 326 PPI

As you can see by comparing the 32 inches Full HD TV and the iPhone 7, the iPhone 7 clearly wins in terms of pixel density even though the screen is a lot smaller than the one on the TV. This is the reason why you are able to perfectly read, write and use the iPhone 7 even though the screen is a lot smaller.

What Is DPI In Printing?

Jim Carrighan — July 17, 2018

When you need to print a photo or an email occasionally, you usually aren’t concerned with the resolution of the printer that you are using. The truth is that even the most affordable printers can make all documents look professional. And even if you have a photo printer, you shouldn’t have any problems in what concerns to the resolution.

Looking for an inches to pixels converter?

So, What Is DPI In Printing?

DPI stands for dots per inch. Since you’re not an expert on the area, let us try to explain to you.

Whenever you need to print a document or a photo, your printer will need to apply the toner or the ink onto the paper. The more ink it can put into a square inch, the better the result of the document or image will be.

Printers usually have a DPI up to 2400. Some have a DPI even bigger. So, let’s say that your printer is 600 DPI. What does this mean?

Simply put, your printer will fill 600 dots both horizontally as well as vertically in every square inch of your sheet.

So, to the question what is DPI in printing, we can say that it is the dots per inch that your printer allows you to make on a sheet.

However, not all printers are the same and you may have one that has a larger resolution on one side. For example, the DPI of your printer can be 600 X 1200 DPI. Usually, and up to a certain limit, the higher the resolution your printer features, the more sharp and crisp will be your image or document.

Is It Possible To Optimize The DPI?

The truth is that there are a wide variety of printers on the marker. Each one has the ability to place dots of different shapes, intensities, and size onto a specific page. Ultimately, you can get a completely different image when you change all these settings.

Some of the more expensive printers actually allow you to optimize the DPI print process. So, basically, these printers optimize the areas where they do their ink drops so that you can get a better image.

What Is DPI In Printing For The Casual User?

The truth is that when you are a casual user, you don’t even need to think about optimizing your DPI. In fact, it will probably be just a waste of ink. While your photos could be better, the truth is that it will probably be just enough.

What Is DPI In Printing When You Work With Photos And Images Professionally?

When you need to regularly print images or photos that need to look at their best, as if you are a photographer, for example, you should make sure that your printer has 1200 DPI. So, this means that you have almost the entire printer market to make your choice. After all, most printers already include this DPI and this is more than enough.

However, if you are a professional photographer, you may need a higher resolution printer. If this is your case, you should probably look for a printer that features 2880 X 1440 DPI or higher.

Learn To Read The Inches To Pixels Conversion Chart

Jim Carrighan — July 17, 2018

When you are working with images and resizing them, it’s important that you understand the difference between inches and pixels. After all, these are the types of measurements that you will need to use whenever you are resizing your images or photos.

One of the main questions that most people tend to have is related to how they can use a inches to pixels conversion chart and how they can interpret it. The following inches to pixels conversion chart is the one you should use when you want to print your images.

But how can you make sure that when you are resizing your images, they will display correctly?

In order to know this, you need to make sure that you know the Dpi that your scanner or printer is using. In case you don’t know, Dpi is simply the number of dots per inch or the pixel density.

When you want to print an image, for example, you may have the ability to choose the Dpi that you want to use. You can use a Dpi of 60, 75, 96, 120, 150, 200, 300, and 600.

But why is the Dpi so important when you simply want to use a inches to pixels conversion chart?

The truth is that in order to use a inches to pixels conversion chart, you need to know the Dpi that you will use. This is the only way that you have to ensure that you will get the image exactly as you want.

One of the things that you will be glad to know is that there are several different free online calculators that allow you to immediately know the number of inches. When you are using one of these calculators, you usually only need to insert the inches number and then choose the Dpi. Then, the calculator should be able to give you the number of pixels that you are looking for.

Using An Inches To Pixels Conversion Chart

As you already know, in order to determine the number of pixels, you will need to know the Dpi that you’ll use.

Try out our inches to pixels converter.

So, let’s say that you want to convert 15 inches into pixels. By using the three simple rule, you’ll be able to manually calculate the number of pixels. However, as you also know, the final number of pixels that you get depends on the Dpi that you want to use. So, what we are going to do in this example is that we are going to convert the 15 inches into pixels using the different Dpi’s we mentioned above.

When Dpi is 60

1 in = 60 pixel (X)

15 in = 15 × 60 pixel (X) = 900 pixel (X)

When Dpi is 75

1 in = 75 pixel (X)

15 in = 15 × 75 pixel (X) = 1125 pixel (X)

When Dpi is 96

1 in = 96 pixel (X)

15 in = 15 × 96 pixel (X) = 1440 pixel (X)

When Dpi is 120

1 in = 120 pixel (X)

15 in = 15 × 120 pixel (X) = 1800 pixel (X)

When Dpi is 150

1 in = 150 pixel (X)

15 in = 15 × 150 pixel (X) = 2250 pixel (X)

Quick conversion from pixels to inches.

When Dpi is 200

1 in = 200 pixel (X)

15 in = 15 × 200 pixel (X) = 3000 pixel (X)

When Dpi is 300

1 in = 300 pixel (X)

15 in = 15 × 300 pixel (X) = 4500 pixel (X)

When Dpi is 600

1 in = 600 pixel (X)

15 in = 15 × 600 pixel (X) = 9000 pixel (X)
