Questions about preparing a photo
How many pixels does a photo need for a print?
At the ArtzFolio standard of 100 pixels per inch, multiply each side in inches by 100. A 16 x 24 inch print needs 1600 x 2400 pixels and a 24 x 36 inch print needs 2400 x 3600.
What is crop loss?
When the shape of the photo differs from the shape of the print, part of the picture is trimmed to fit. The crop loss calculator shows how much for the shape you have.
Which shape matches the most listed sizes exactly?
1:1. 8 listed sizes have exactly that long-to-short ratio: 6 x 6, 8 x 8, 10 x 10, 12 x 12, 16 x 16, 20 x 20, 24 x 24, 28 x 28 inches.
How do I check my own photo?
The photo quality checker tests a photo in your browser, and nothing is uploaded. The photo size check does the same arithmetic from a pixel size you type in.
What do I do once the photo is ready?
Open the studio, enter the width and height, and check the live price. Printed photo frames are listed in 27 sizes, so you can order photo frames online at a size that suits the picture.
