Printsize

Turn pixels into print sizes, crops and mat borders. Works fully offline.

Printsize answers one question before you order a print: how big can this picture go, and how should it be cropped and framed?

Type the width and height of your image in pixels, or tap a megapixel preset, and choose a DPI from 72 to 600. Printsize shows the print size in inches and centimeters right away, together with a small picture of the print inside a mat inside a frame, drawn to scale.

What you can do

- Print size at a DPI: see the size in inches and centimeters for any pixel size. - Target print size: enter a paper size and get the DPI for two cases. Fit whole image keeps every pixel and may leave white space. Fill the paper covers the sheet and tells you how many pixels remain after cropping. - Quality tiers: three thresholds (defaults 300, 200 and 150 DPI) that you can edit. For each tier the app lists the largest print your image can reach. - Crop to aspect: pick 1:1, 5:4, 4:3, 3:2, 16:9 or your own ratio, in landscape or portrait. See the pixels kept, the percentage lost and which sides are cut, and move the crop toward one side. The cut-away area is dimmed on the drawing. - Mat and frame: enter the print size and the frame opening to get the border on each side. An optional extra bottom border gives the traditional bottom-weighted look, and the drawing warns you when the print is larger than the opening. - Standard sizes: the DPI your image would reach on 4 x 6, 5 x 7, 8 x 10, 8.5 x 11, 11 x 14, 12 x 18, 16 x 20 and 20 x 30 inch paper and on A6, A5, A4, A3 and A2, in fill or fit mode. - Saved images: keep up to 30 pixel sizes you print often and load them with one tap. - Inches or centimeters for entering sizes, a plain-English guide, and a share button for the result as plain text.

Every number is simple arithmetic on the values you enter, shown with the working you can check by hand. The quality tiers are general guidance; your print lab or printer may ask for different values.
