3.5 x 2.5 photos are also commonly referred to as wallet-size photos. They are an ideal size to print if you want to share printed photos with a large number of people. Most photography studios offer wallet sizes for purchase. However, you may wish to print your own wallet-size photos to hand out to friends and family. Using most photo editing software, it is possible to convert photos to 3.5 x 2.5 size for printing.
Open your editing software and create a new document.
Set the canvas size to 3.5 x 2.5 inches.
Open the photo you want to print 3.5 x 2.5 size.
Paste the photo onto the 3.5 x 2.5 canvas.
Re-size the photo if necessary by selecting it and scaling it down to fit within the canvas. Some editing software will automatically re-size photos to fit the new canvas size. The photo is now ready to print.
To save photo paper, you can print multiple photos on one page. To do this, save all the photos you want to print in the 3.5 x 2.5 size. Create a new image canvas in an 8.5 x 11 size. Paste as many photos as you can fit onto the new canvas and print from there.
Always be certain you have the rights to any photos you are printing.
