Oh dear, assuming the 254 represents pixel dimensions, that would not be suitable for much more than a locket sized photo, possibly a grainy print at 2" square (5cm square).

You are quite welcome.


To calculate the DPI for a printed photo is quite easy. If you are wanting to print a photo of 8" X 10" and the print service request 300 DPI, the photo file you would need to send would be a minimum of 2400 Pixels X 3000 Pixels. Similarly if you wanted a 5" X 7" photo printed the required pixel dimensions would be a minimum 1500 Pixels X 2100 Pixels.
