We're the Perfect Print team. Sometimes an application wants exactly one photo β a single ID or application photo to mail or upload β and that one photo turns out to be surprisingly annoying to produce. A photo booth at the pharmacy or drugstore prints a strip of four to six at once, so you pay for a full set and waste most of it. Print a single photo at home instead and the printer happily blows it up to fill the page, so it comes out far bigger than the size on the form. This article is about getting one good photo (plus a couple of spares) at the exact required size, without paying for a sheet you don't need.
Why one photo is harder than a whole set
The frustrating part is that the size you need is small β often something like 2 x 2 inches (about 51 x 51mm) for a square ID photo, or a small rectangle for other forms β yet a single image sent to a printer almost always scales up. Printers default to filling the paper, so one photo on a sheet becomes a giant headshot rather than the small, precise rectangle the form asks for. Booths solve the cost-per-print math by giving you a full strip, but then you've paid for six when you needed one, and you can't choose which shot you like.
What you actually want is the opposite arrangement: keep each copy at the real required size, and place as many copies as you need on one sheet β one, or one plus a few spares β so nothing is wasted. Always check the exact size your form or agency requires first, since it varies by document.
Why cropping in a photo app can't fix this
The natural reaction is to crop the photo to a square in the photos app and print that. But a crop only changes the pixels in the image; it never decides how many inches the print becomes on paper. The number of inches is set at print time, and with the default fit-to-page behavior that single image expands to the sheet. You can have a perfectly square crop on screen and still get a print that's nowhere near 2 inches across. That gap between the on-screen crop and the physical print is exactly the problem.
To fix it, the photo has to be locked to a real, physical measurement before it ever reaches the printer. That's what Perfect Print is built to do, entirely on your phone.
Lay out one photo (plus spares) at the exact size
The flow is short. Pick a paper size β a letter sheet works at home or a print shop, and a 4x6 photo print works at a kiosk β choose your photo, then enter the photo size in inches (for example 2 x 2 inches; you can go down to the millimeter if your form lists a metric size). The image is placed at actual size, and you can drop several copies of it onto the same sheet. Put down just one if that's all you need, or one plus two or three spares to guard against a misfeed or a smudge.
Save the image, then print at home or upload it to a print shop, and set printing to actual size (100%) so it comes out at the inches you specified instead of stretching to the page. Because you only print the copies you'll use, the cost per photo stays tiny compared with buying a full booth strip. After printing, lay a ruler against it to confirm it's the true size the form wants.

I only need one photo β can I really avoid buying a whole strip?
Yes. Size the photo to the required dimensions in Perfect Print and place just one copy (or one plus a couple of spares) on the sheet, then print at 100%. You pay for a sheet of paper instead of a full booth set.
Why does my single photo print too big?
Because printers default to fit-to-page and stretch one image to fill the sheet. Lock the photo to a real size in inches first and print at actual size (100%) so it stays small and exact.
How many spares should I add?
Two or three is usually plenty β enough to cover a misfeed, a smudge, or a second copy of the same form. Since they all sit on one sheet, the extra copies cost almost nothing.
What size should I use?
It depends on the document. Many U.S. forms that accept a submitted photo use 2 x 2 inches, but always check your specific form or agency. Perfect Print lets you enter any size down to the millimeter.
