"It printed at the wrong size." "I want this photo at exactly 2 x 3 inches." Phone photos are usually printed to a preset like 4x6, so choosing an exact measurement is surprisingly hard. This article shows how to print an image at its actual size — measured in inches or centimeters — using only your phone.
Why phone prints come out the wrong size
Print a phone photo directly and it's usually fit to a fixed preset like "4x6." Convenient, but it gives you no way to set an exact measurement — like "make it 2 inches tall by 1.5 inches wide" or "print this image at a true 4 inches."
You can set exact dimensions in Word or Photoshop on a computer, but opening a PC just for that is a hassle. That's where a print-size app on your phone helps. The app we make, Perfect Print, lets you place an image onto a page at the exact size you specify — in inches or centimeters — ready to print.
How to print an image at actual size
The steps are simple. Here they are in four steps, using Perfect Print as an example.
Choose a page layout
Open the app and pick your page. Perfect Print lays your images out on an A4 page (plus photo sizes like 4x6), which prints cleanly on most home and office printers.
Pick your image
Choose the image to print from your camera roll. You can also place several images on a single sheet.
Enter the size in inches (or cm)
Type the image's height and width. Enter "3 in tall x 2 in wide" (or in centimeters) and it's placed at true scale. You can move and rotate it freely.
Save and print
Save the finished image, then print it on a home or office printer. Print at actual size (100%) — not "fit to page" — and it comes out at exactly the size you set.
Getting the size exactly right
The one rule that matters: when you print, choose "actual size" or "100%" in your printer dialog, not "fit to page" or "scale to fit." Fit-to-page silently resizes the image, which is the most common reason a print comes out too big or too small.
Perfect Print lays images out on an A4 page. If your printer is loaded with US Letter paper, just keep the print scale at 100% and the image still comes out at the exact inch/cm size you entered — only the surrounding margins differ.
When it comes in handy
- Making and printing a passport or ID photo yourself (e.g., the US 2 x 2 inch passport size)
- Printing artwork, stickers, or fan goods at true size
- Printing business cards (3.5 x 2 in) or labels at fixed dimensions
- Matching multiple photos to the same size for an album or frame
Summary: print to scale, right from your phone
Phone photos default to preset-based printing and struggle with exact measurements. But with a print-size app, you just pick a layout, enter the size in inches or cm, and save. No PC required — print at the true size you want. If sizing has tripped you up before, try Perfect Print on your next print.

Frequently asked questions
Can I print an image at an exact size using only my phone?
Yes. With a print-size app like Perfect Print, you pick a layout and type the height and width in inches or centimeters to create true-scale print data — no PC needed.
Any tips so the printed size doesn't drift?
Set the print option to "actual size," "100%," or "no scaling." Choosing "fit to page" auto-scales the image and throws off your measurements.
Can I measure in inches instead of centimeters?
Yes. Perfect Print lets you enter image dimensions in inches or centimeters, so you can work in whichever unit your size requirement uses.
Is there a cost?
Perfect Print is free to download and use. It works on both iPhone and Android with no sign-up (printing itself costs the usual printer or print-shop fees).
