How do I crop a photo in the following sizes?

I need to have photos printed at costco in 5x7, 4x6 and 2.5 x 2.5?

I have irfanview and photoshop but still am looking for a way to crop a photo for the above sizes...

Vista's built in program can do it.

not on vista...xp....

Use the 'Canvas Size' command in the Image menu.

Let's say your image is originally 800x600 and you want it in 4x6 proportions. So that's an aspect ratio of 6 / 4 = 1.5.
Now divide the longer side by the aspect ratio: 800 / 1.5 = 533.
In Canvas Size replace 600 with 533, and make sure you anchor your photo up or down if necessary so you don't cut off someone's forehead for example.
Finally your photo should be 800x533.

Why can't you do that with Photoshop?

1. Use Crop tool (Press C)
2. At the top bar, put 5 in the 'Width' box and 7 in the 'Height' box. Make sure it's in inches.
3. Drag your cursor to crop whatever you wanted to crop.

In Photoshop select the cropping tool and then fill out your dimensions:



Then proceed to drag the cropping tool on your photo until you get it the way you want.

You don't need to resize photos when you get them printed. When you get them printed costco will do the resizing for you when you specify which size you want.

Maybe I'm completely misunderstanding your question.

i want to select a subsection within the picture that is 2.5x2.5...

i think the answers above give me a good lead...

Just make sure you crop the image to the correct height/width ratio. Just do the pixel math with the dimensions...

Also, try not to crop it below a density of 300 pixels per inch (e.g. 4x6" prints should ideally be at least 1200x1800 resolution).

They do but then the picture will come out not looking the same since not all camera's take pictures in the same aspect ratio as the printout. It will be stretched/compacted in some respect.

An easier way without having to do any math is to simply use the Marquee Tool and set it to "Fixed Aspect Ratio" style.



Just enter your print sizes as the aspects (4x6, 5x7, etc.) and Image -> Crop after you select.

That's a longer way of doing it than just using the crop function and specifying final size and dpi like the person above posted.

I disagree, using the Fixed aspect ratio means you put your numbers in once use the marquee tool and crop away to your hearts content. no math, no mistakes! Perfect crops everytime!

Are you missing the point that setting your desired final size with the DPI in crop is using a fixed aspect ratio. The only difference is that it's all done in one step, rather than setting the aspect ratio, making the selection, cropping and then using image size. Launch photoshop and try it.
