Wallet size pictures, crop size ?

Someone tell me what the crop size numbers I should put in for adobe photoshop, and I don't think ppi matters that much but also what should I use as well ?

I'd say about 2 x 3 inch.

Seems Photoshop elements has a preset for 2 x 2.5 in.

Here are the aspect ratios to use while cropping from MPIX.

Aspect ratios for Mpix prints:

For a 4 x 6" print: Your image should have an aspect ratio of 1:1.5
For a 5 x 7" prints: Your image should have an aspect ratio of 1:1.4
For an 8 x 10" print: Your image should have an aspect ratio of 1:1.25
For a 16 x 20" print: Your image should have an aspect ratio of 1:1.25
For a 20 x 30" print: Your image should have an aspect ratio of 1:1.5
For a Wallet-size print: Your image should have an aspect ratio of 1:1.4

Wow! This is an old thread!

THe crop size IS 2.5 x 3.5.
I don't understand why people are saying "it should be about xxx" or "the ratio is xxx". You asked for the EXACT crop size in photoshop. The crop size is 2.5 x 3.5.

+1 2.5 x 3.5 at 300 dpi
I use 300 because people look at wallet sized prints closely.

2.5 to 3.5 wallet print out size correct?
