Standard Photo Sizes
Nowadays, printing photos in standard sizes may be a bit of a 
challenge because you no longer print through the use of the age-old film strips and then come-up with negatives prior to printing.
Most photos taken from a digital camera, which is the commonly used camera these days, do not fit into the standard photo sizes. So what you need to do is to crop the pictures according to the size that you want, usually based on the frame size of your choice.
In order to come-up with the right photo sizes, you first need to know the standard sizes that photos come in.
Standard Photo Sizes
Photo sizes usually come in inches but there are conversions available on the internet if you need sizes in millimeters. This will help you decide on what paper size to use when printing your photos.
Some of the most common photo sizes and their equivalent paper sizes are as follow:
4 x 10 = 102 x 151 millimeters; paper size is A6 or one that measures 105 x 148 millimeters
5 x 7 = 126 x 177 millimeters; paper size is A5 or one that measures 148 x 210 millimeters

You can also create your own photo frames to give them a touch of your own creative imagination as well as a bit of your personality.
