You load 4 x 6 photo paper, print a picture from your phone, and it comes out small in a corner, cropped at the top, framed in white, or the printer complains about the paper. Phones don't always tell the printer what paper you're using, and phone cameras shoot in a shape that doesn't quite match common print sizes. This guide sets paper size and type on iPhone and Android, explains cropping, and helps you get borderless prints where your printer supports them.
What you might be seeing
- A small photo printed on a large page
- Heads or edges cut off the picture
- White borders when you wanted borderless
- Paper size mismatch errors on the printer
Common causes
- Wrong paper size selected
- Print options often default to Letter or A4, so the printer treats the photo as a full-page job.
- Aspect ratio mismatch
- Phone cameras usually shoot in a 4:3 shape, while 4 x 6 prints are 3:2, so something gets cropped or left blank.
- Tray settings on the printer
- Many printers store a paper size for each tray, and a mismatch makes them stop or scale the image.
- Borderless not available
- Borderless printing only works with certain printers and paper sizes, and has to be turned on.
How to fix it, step by step
Work through these in order and test a print after each one. Most people are done within the first few steps.
Set the tray paper size on the printer
Load the photo paper as the printer's manual directs, then check the control panel. Many printers ask for the paper size and type when you load paper; choose 4 x 6 in (10 x 15 cm), or whatever you loaded, and a photo paper type. If it doesn't ask, find the paper or tray setting in its menu. A printer that thinks plain Letter paper is loaded will scale or reject the job.
Choose paper size on iPhone or iPad
In Photos, open the picture, tap Share, then Print. In the print options, set Paper Size to match the paper you loaded, and if your printer offers paper types, pick photo paper too. The preview updates to show how the picture will sit on the page, so check it carefully before tapping Print.
Choose paper size on Android
Open the photo, tap the share or menu button and choose Print. In the print preview, tap the small arrow under the printer name to expand the options. Set Paper size to your photo size and, if shown, Orientation to match the picture. The Mopria Print Service often adds choices such as paper type and borderless printing, though exact options depend on the service and printer.
Crop the photo to the print shape
To control what gets trimmed, crop the picture yourself. In the iPhone Photos app, tap Edit, choose the crop tool, then the aspect ratio button, and pick 3:2 for 4 x 6 prints or 7:5 for 5 x 7. Most Android gallery apps have a similar crop tool with ratio presets. Save the crop, or a duplicate, and print that version.
Turn on borderless printing
Many inkjet photo printers support borderless prints on specific paper sizes. Look for a Borderless option in the phone's print options, the Mopria settings or the manufacturer's app, and on some printers in their own menu. If the option is missing, your printer or chosen paper size may not support it, and a thin white border is normal.
Use the manufacturer's app for photo layouts
If the built-in print options are too limited, the manufacturer's official app usually offers photo-specific sizes, borderless control and paper selection designed for its printers. It's especially handy for fitting several small photos on one sheet, or for special media such as photo sticker sheets or square paper that the phone's standard options don't list.
Test on plain paper first
Photo paper is expensive, so cut a sheet of plain paper to the same size and run a test with your settings. Check that the picture is centered, cropped as you expect and the right size. Once it looks right, load the photo paper and print again without changing anything. Keep the test sheet as a reference for future prints.
How to keep it from happening again
- Set the paper size every time you change paper
- Crop photos to the print shape before printing
- Keep the printer's tray settings matching the loaded paper
- Store photo paper flat in its packaging
Common questions
Why does a 4 x 6 print cut off part of my photo?
Most phone photos are a squarer shape than a 4 x 6 print. To fill the paper without white bars, the printer has to trim some of the top and bottom, or the sides of a landscape shot. Cropping the photo to 3:2 yourself before printing lets you choose what stays in the picture.
Why does my photo print on a full sheet when I loaded small paper?
The print options are still set to Letter or A4, so the printer lays the photo out as if on a full page and may pull from the main tray instead of the photo tray. Change the paper size in the print options and check which tray the printer uses for photo paper.
Can I print phone photos larger than 4 x 6?
Yes, if your printer takes larger photo paper such as 5 x 7, 8 x 10 or full Letter or A4 sheets. Set the matching paper size and crop to the right shape. Larger prints show more detail, so print the original photo rather than a copy saved from a messaging app, which is often compressed.
