Unlike popular believe, however, megapixels is not the be-all-and-end-all of digital photography. However having said that some photographers who shoot professional photos and want their pictures to be able to retain a lot of detail even when cropping would love the idea of being able to shoot with 24 megapixels or even 36 megapixels. There is some relationship between print sizes and the megapixels. Look at a billboard from a distance. It looks bright and sharp.

Can you take a guess what is the dpi dots per inch at which it may have been printed? About 72!

Resolution and print sizes explained

The minimum distance at which a billboard is seen is more than 20 feet. At that distance it is impossible to notice the pixels. If there is a picture on a wall and you are looking at it from a distance of say one meter, the ideal dpi is A magazine is normally printed at a resolution of dpi. Enough said about dpi but what is the relation between dpi and megapixels? What is the perfect megapixels count that can give you that dpi resolution without burning a lot of useless megapixels?

How to calculate print size for your photos

Multiply x 8 that gives us pixels and multiply 12 x that gives us So x pixels is the exact pixel size of the image that you need in order to print an image with dpi. Means, it is perfect for a print size of Certainly more than what an average user would ever need for printing everyday photos.

Photo labs recommend at least dpi input for normal prints. But megapixel is not the end of the story here. Using good optics, low ISO setting, correct exposureproper depth of fieldkeeping camera shake free and proper post processing is critical to get quality print out. If you follow good shooting practices, virtually any of the currently available DSLRs on the market should be able to produce quality prints to match the maximum size a consumer inkjet can produce.

In general, bigger sensors produce better image quality. Which results cleaner and better images. You can read more on various sensor sizes here. With this massive Read more on megapixels here.

So I should hide this article from my wife whilst trying to justify replacing my D with a new D Also "standard" 35mm film works out at around 12Mp, back when digital first came out and cameras were between 0. Your 35mm stats are the upper range of film not the norm!

This chart outlines how big you can blow up your digital pictures. This chart was created and sent to us by one of our students. To use this chart find the resolution of your image and multiply it to find out how many megapixels the image is. It should be noted that the image enlargement size recommendations above are on the conservative size and will allow for optimal enlargement capabilities with the best and crispest possible picture.

However, you can still blow your photographs up further if you don't mind loosing a little bit of crispness. For example you can enlarge a megapixel print to Better yet, you can blow up a 10 megapixel print to 20x30 for a good quality print. If you're interested in learning more about this. Have a look at our online course. More photography resources. Photography Glossary. Skip to content Many people who use digital cameras want to know how large they can blow up or enlarge their photographs based the megapixel count of their camera.

Is More Megapixels Necessary? The casual photographer will see no difference to a slight difference when compared to Superb. Better than Good, but not as good as Excellent. The typical photographer will be very happy with prints of this quality. Quality will depend on the individual picture. For larger size prints the typical photographer will find them acceptable, but the sharpness will not be as high as a Good quality print. Compelling subject matter may trump the loss of sharpness.

But doesn't it always?!Does a chart exist so i can easily see what the different megapixels will give me in terms of file size and print size Megapixels file size range max quality print size 3. For print size, using the image dimensions, divide by You can get by with less than dpi, but image quality suffers. There are interpolation plugins and actions available to upsize an image prior to printing.

You can get bigger prints this way and the results are acceptable to many Pros. File size, on the other hand, is very subjective. Since most digipics are jpeg compressed, there is no fixed number of bytes per megapixel. As uncompressed tiffs or bitmaps, multiply the megapixels by 3 to get bytes.

Twice that for 16 bit tiffs.

Tiff compression can reduce this to about 6mb for 8bit and 12mb for 16 bit tiffs. Jpeg compression greatly reduces this, but the amount of savings depends a great deal on image content. More detail means less compression means bigger files. The opposite is true as well. Less detail At the highest quality setting, my 3. At a normal print viewing distance, the typical human eye can see up to dots per inch.

That's the best you need to do. However, dots per inch is excellent print quality and many people consider dots per inch to be acceptable. So, start off by figuring dpi for acceptable quality up through dpi for "perfect. Once you know at how many dpi you intend to print, just take your desired print size and multiply each dimension by that number. Thus, for a 4" x 6" print at dpi quality, multiple the 4 and 6 by The result is that you need x pixels in your image.

That's really all there is to it. Now, x pixels comes to a product ofpixels. Thus, a 1. At dpi, you'd require x or 2. As another example, a dpi 8" x 10" print would require x pixels, which comes to a product of 5 Mpixels. You couldn't even achieve a true dpi print in this size, as no 7. While using a to DPI value might work as a rule of thumb, you really can't assume one 3 megapixel image is as good as another. For example, the Canon D30 will produce a much better print than a consumer digicam with the same number of pixels.

One measure that's useful is the resolution as measured from photos of a standard resolution chart. This site and some others include such information in each camera review. Another measure is noise.Below are the suggested number of megapixels to use for common print sizes.

If you crop images a lot, increase the minimum suggested megapixels. Some cameras automatically reduce the size of an image if you switch to certain modes, such as high ISO. If you plan to do your own printing, get a photo printer and use high quality photo paper to obtain the best results.

I actually found a pretty convenient iPhone app for this purpose.

It gives the largest printable image based on desired quality and pixels per inch. Photo Rez Sizer. Check it out. I find all of this confusing as to pixel sizes and print sizes. Also, the information on various sites and software vendors dealing with photo resizing is inaccurate more so as to pixels vs. You can increase the DPI using your photo image software, then open the picture in powerpoint as if you were working on a slide package.

Now click on format picture and just change the picture size. Leave aspect ration alone and relative to original picture size alone. Also, I find that increasing some of the pixels gives room for cutting pictures to fit frames. The problem is with these dumb manufactures making odd size frames vs.

What a headache! My best advice would be to rescan the images at or near the desired resolution.

Inkjet printers. Photo developers. You may also like.One of the most confusing things for a new photographer is understanding image size, resolution, and printing. As a photographer you will already have confronted the term megapixel when you first purchased your camera. While technically a megapixel is equal to 1, pixels, in reality, camera manufacturers round this number to 1, when stating how large an image the camera will capture.

So, my camera, for example, is stated to capture This information tells you nothing about the actual pixel dimensions of the image — it only tells you the total number of pixels that comprise the image. My camera, like most dSLRs, captures images with an aspect ratio of 1.

So the ratio comparing the number of pixels along the long edge of the image, to the short edge is Each full size raw image is x pixels in dimension. You and I might call this You can check the width and height of an image using your photo editing software. The image above shows this information dialogue box. You can see these pixels if you open a photo inside a photo editing program and zoom in until you see single blocks of color like below.

Each of these is a pixel. Typical printing ppi values range from to ppi, although some high-end magazines may require images which are ppi. So, for example, if you want to print an image 4 x 6 inches at ppi, then you need a file that has at least 4 x pixels along its short side and 6 x pixels on the long side. So, it needs to be at least x pixels in size. The result is 2, x 3, pixels, which is the size image you need to print an 8 x 10 at ppi. This is a screenshot from the MpixPro.

Their printer outputs at ppi but can handle ppi images — other services may differ — so always check before preparing your images:. Use the crop or resize feature in your software to size the image to the desired width and height, and the ppi resolution. Here an image cropped to a size of x pixels is being adjusted from 72 ppi to ppi in preparation for printing at ppi. There is no resampling required as the image is already the correct dimension and only the resolution requires adjusting. Photoshop, like other applications, will also crop an image to a fixed size and resolution if you type these value into the tool options bar when you have the Crop tool selected see below.

If your image is smaller than the typed dimensions then the image will be enlarged using the default resampling method as it is cropped. When it comes to displaying images on the screen you need far less pixels than you do for printing. This is because the density of pixels on the screen is far less than what is required for printing.

So, for example a typical monitor is by pixels in size so, to fill the monitor you only need an image that is by pixels in size.Here are conversion numbers for common photo sizes. And while you're at it, try editing that photo to really make it sing. Not seeing the size you want in our chart? No problem. This chart gives you international standard print sizes.

A0 is one square meter and each consecutive size is half the size of the one before it. ISO standard print sizes are used less frequently in the U. For example, A7 is the size of a note card.

Edit a photo with PicMonkey.The dimension in pixels Image Size is the important detail for using any image. Around pixels per inch is an optimum and proper printing goal for photographs.

Many 1-hour photo lab digital machines are usually set to print at up to pixels per inch, but it won't hurt to always provide pixels to print dpi. FWIW, I'm old school, and I learned the term for printing resolution as "dpi", so that's second nature to me, it has simply always been the name of it. Some do call it ppi now, same thing, pixels per inch. Printers do have their own other thing about ink drops per inch which is about quality of printing, not about image resolutionbut here, we're speaking about printing resolution of image pixels.

The photo printing shops where we order prints will offer a paper size, and will fill that paper with your image will ignore your dpi number already in the image file, and will recompute their own necessary "pixels per inch" value, to scale your image to their paper size.

If you order 8x10 inches, you will get 8x10 print size. Planning ahead to crop image to match paper shape, and to provide enough pixels so that the result will be to pixels per inch is a very good plan. If your image dimensions are too large, the photo shop will first resample it to this smaller requested size.

That's not necessarily a problem, except the too-large image will be slow to upload.

Or, if too small insufficient pixels providedthe print quality will be lower, and the lab may refuse worst cases. But if the image shape does not match the paper shape, the excess image outside the paper edges simply disappears, results may not be what you expected. If printing yourself at home, the Print menu in your photo editor normally does use the file's scaled image dpi number pixels per inch to size the images on paper. But it typically will also allow changing that dpi, called scaling to fit the paper size.

The dpi number that your digital camera initially stores in the file is far from meaningful, it is just some arbitrary number, which will print SOME size, but not likely to be your own printing goal. Hopefully, you have already properly scaled the image for your selected paper size.

However, most photo editors will also provide an option to "Scale to fit media" or "Best fit to page", which will scale the image to fit the specified paper size similar to A above. This can be borderless if so specified in the printer Properties. This scaling will print at a new dpi which will fit the paper size. But it will not necessarily fit the paper "shape", which requires cropping attention done by you. When the print and paper shapes differ, a print shop "fit" typically fills all of the paper, cropping one dimension to leave no white border in the other.

A home photo editor "fit" typically is the opposite, not cropping at all, but leaving thin white space in one dimension if it doesn't fit precisely. Either way, it is good if your plan properly prepares the image for printing. Different paper sizes are different shape.

And we need to provide the necessary pixels.
