Printing size help

[joel222]

I'm going to get a few pictures printed but i'm unsure if I need to re-size them. They are 3456 x 2304, will this size be ok for 6x4 or 7x5 photos?

6x4 yes - 7x5 will need a crop to resize. I used to have a 350d so I am trying to remember.

the canon 350d used a 3:2 ratio so that would be a 6x4.

The general guideline is 300ppi (pixels per inch) for printing using an outside lab. Some will accept lower resolutions, but it's a good basis to work from.
As Tom said, the ration is 3:2 so 6x4 is fine, but 7x5 will need cropping to fit.
