Print size preview

Drop your photo, pick a paper size and a DPI, and see a to-scale diagram of exactly how much of the page it covers — whether it fills the sheet, leaves a wide border, or is actually too big to fit at that resolution.

This is a to-scale diagram of the photo against the page, not your screen's true physical size.

How it works

Drop your photo

Any image.

Choose a paper size and DPI

A4, Letter, A5 or common photo sizes.

Exactly how the photo sits on that page.

See the fit before you print

How big a photo actually prints depends on both its pixel dimensions and the DPI you print it at, and it's easy to lose track of the relationship between the two. This tool draws a proportional diagram — the paper as an outline, the photo drawn to scale inside it — so you can see at a glance whether it fills the page, leaves a border, or doesn't fit at all at your chosen resolution.

What the diagram shows

The image is drawn at its true size relative to the paper outline, both scaled down together to fit the screen. If the photo is smaller than the page it appears centered with visible white space around it; if it's larger, it extends past the page's edges, making an oversized image obvious immediately rather than as a surprise from the printer.

An honest limit: this isn't your screen's actual physical size

No website can reliably know your monitor's real pixel density, so this is a scaled proportional drawing, not a true 1:1 preview on your screen. What it does show accurately is the relationship between the photo and the page — how much of it is covered, and whether the image resolution is enough for that page at your chosen DPI.

Checking before you send it off

Catching an oversized or undersized image here, before sending it to a print shop or a home printer, saves a wasted print and a second trip — a quick visual check against the page is often enough to know something needs fixing.

Your photo is measured and drawn entirely in your browser. Nothing is ever uploaded.

Frequently asked questions

Does this show the actual size on my screen?
No, no website can reliably know your monitor's real pixel density. It's a to-scale proportional diagram of the photo against the page, not a true physical-size preview.
What does it mean if the photo is bigger than the page outline?
At your chosen DPI, the photo's pixel dimensions convert to a physical size larger than the paper — you'd need to lower the DPI, use a bigger page, or accept it being cropped or scaled down to print.
What DPI should I choose?
300 DPI for sharp, close-up prints; 150 DPI is often fine for something viewed from a bit of distance; 72 DPI is a screen resolution, rarely enough for a real print.
Can I check custom paper sizes?
Currently it covers A4, US Letter, A5 and common photo print sizes (10×15 cm, 13×18 cm).
Why does the photo look small with lots of white space?
That means your chosen DPI turns the photo's pixels into a smaller physical size than the page — normal for a photo destined for a smaller print, or fine if you plan to leave a border.
Is my photo uploaded anywhere?
No. Everything happens entirely in your browser.
