How to Print 4x6 Photos on Letter (8.5x11) Paper From iPhone

Photos on iPhone has no print-size setting, so iOS enlarges the photo to fill most of a letter sheet. For a real 4x6, set it to 4 by 6 inches in Apple’s free Pages app, or print it with an app that sends it at 4x6, such as iPrint Printer on an AirPrint printer.

If your printer takes 4 x 6 photo paper, you may not need either: Photos prints onto it directly. The sections below cover that case, the free Pages method, free layout websites and their catch, then the app, and finally A4 paper and cutting.

Why your iPhone prints a 4x6 photo full-page

Apple’s own steps for printing a photo are short: open it in Photos, tap the Share button, tap Print (the iPhone User Guide gives the same steps for iOS 26 and iOS 27). The print screen then asks for a printer and the number of copies. There is no field for the size of the print. With nothing to go on, iOS sizes the photo to the paper the printer reports, which on an 8.5 x 11 inch sheet means a picture several times larger than 4 x 6.

Making the photo smaller first doesn’t help. A photo file holds pixels, not inches, and printing from Photos or Preview still sizes it to the paper; the guide to resizing a photo to print explains why, and what does work.

If you have 4x6 photo paper: just use Photos

With 4 x 6 photo paper in the printer, Apple’s own route is the right one and it costs nothing:

Load the 4 x 6 paper where your printer’s manual says (some printers have a separate photo tray).
Open the photo in Photos, tap the Share button, then tap Print.
Choose the printer. If the print options list paper sizes, pick the 4 x 6 one.
Tap Print.

Printing on an HP? The HP version of these steps covers its photo trays and HP’s own app.

One thing to know first: an iPhone photo isn’t 4 x 6 in shape. The Camera app shoots 4:3, 16:9 or square, and a 4 x 6 print is 2:3. To decide what gets trimmed, crop the photo in Photos before you print: tap Edit, then the Crop button, then the aspect ratio button, and pick the 3:2 shape (2:3 for a tall photo) if your list shows it. Apple’s guide names presets such as Square, 9:16 and 5:7.

Everything below is for the more common situation: plain letter paper in the tray and no wish to buy photo paper for one print.

Print a 4x6 on letter paper for free with Pages

Pages is Apple’s free word processor, and it lets you set a picture to an exact width and height. It prints the page as you laid it out, so a picture you set to 4 x 6 inches should come out at 4 x 6.

Open Pages and start a blank document.
Check the paper size: tap the More button at the top of the screen, tap Document Options, then Document Setup, and choose Letter (or A4).
Add the photo: tap the Content Hub button in the toolbar, tap the More Options button, then tap Choose Photo or Video and pick it.
Set the size: with the photo selected, tap the Format button, tap Arrange, tap W or H, and type the width and height.
Print: tap the More button, tap Print, choose your printer and tap Print.

Step 4 has a catch. With Constrain Proportions on, Pages keeps the photo’s shape, so typing a width of 4 inches gives a tall 4:3 photo a height of about 5.3 inches, not 6. Crop the photo to 2:3 in Photos first (as above) and the height lands on 6. Turning Constrain Proportions off instead stretches the picture. For a second print, copy the photo and paste it onto the same page, then drag it below the first.

It works, and it’s free. The cost is time: every photo is placed and sized by hand, and every new batch starts again. Measure the first print with a ruler before you print the rest.

Free photo-layout websites

Several free websites take a photo and lay it out at 4 x 6 on a letter-size or A4 PDF, ready to print. Their own instructions tell you to print at 100% or “Actual size”. The iPhone’s print screen offers no such setting for a PDF, so whether the photo comes out at exactly 4 x 6 depends on your printer. Print one page and measure it before you trust the rest.

How to print 4x6 photos on letter paper with iPrint Printer

iPrint Printer adds the step iOS leaves out: you choose the size, and each photo is sent to the printer at that size. It works with printers that support AirPrint, on the same Wi-Fi as your iPhone, and its test page and test photo are free, so you can check both your printer and the size before paying anything.

Open the app (on your Home Screen it’s called Printer) and tap Print Photos. Pick one photo or several.
Tap Size and choose 4 × 6 in.
Set the copies (the row reads Copies with one photo, Copies of Each Photo with several), and set Paper in Your Printer to Letter.
Look at the sheet on screen. The line under it says what will print, such as “2 prints on 1 sheet of Letter”.
Tap Print. The first time, choose your printer.

Two 4 x 6 prints fit on a letter sheet. They lie sideways, one above the other, so a photo that’s taller than wide is turned on the page; cut it out and it’s the right way up. Each print keeps its exact size, with a 3 mm gap between the two to cut along.

The app fills each 4 x 6 with the middle of the photo. Because iPhone photos aren’t 2:3, a little is trimmed: on screen the parts that won’t print are dimmed. To change what’s kept, tap the crop button next to the photo, then drag to move it or pinch to zoom.

Not sure the size will come out right on your printer? Tap Print a Free Test Photo before you print your own. It prints a landscape the app draws itself, not one of your photos, at 4 x 6 on your letter sheet and in the spot your first print would take, so a ruler tells you whether the size is right. When you then tap Print, the app first checks that it can reach your printer, and only after that shows the plans: Unlimited Printing is $4.99 a week, $9.99 a month or $49.99 a year, after a 3-day free trial for eligible new subscribers.

On A4 paper

The steps are the same with Paper in Your Printer set to A4. In A4 countries the app shows sizes in centimetres, so 4 × 6 in appears in the size menu as 10.2 × 15.2 cm (Wallet stays in inches); in the UK the same print is usually called 6x4. A4 is 210 x 297 mm, a little narrower and taller than letter, and it also takes two 4 x 6 prints.

If the prints are for a frame or an album sold in centimetres, choose 10 × 15 cm instead. It’s close to 4 x 6 in but not the same: 10 x 15 cm is about 3.94 x 5.91 inches, a hair smaller each way. Two fit on A4 or letter.

On iPad

An iPad follows the same rule. Apple’s iPad User Guide prints a photo with Share, then Print, and nothing in between sets a size, so a 4x6 photo sent to letter paper still fills the sheet, while 4 x 6 photo paper takes it directly. The Pages method works on iPad too: Pages for iPad sets a picture’s width and height under Format, then Arrange.

iPrint Printer runs on iPads with iPadOS 26 or later. Print Photos, Size and Paper in Your Printer are the same rows as on iPhone, and the larger screen shows each letter sheet and its 4 x 6 prints before you tap Print.

Cut them cleanly

Most printers can’t print to the very edge of plain paper, so a 4 x 6 on a letter sheet always has white paper around it, and that’s what you trim. A paper trimmer gives the straightest edges; a metal ruler and a craft knife on a cutting mat come close. Cut down the middle of the 3 mm gap, then trim each print to its edge.

Plain copy paper works, but photos look flatter on it than on photo paper. Glossy and matte photo paper also comes in letter size, if you print photos often; in the app it’s still Letter.

What the app can’t do

Printers without AirPrint, or USB-only and Bluetooth printers. It prints over Wi-Fi to AirPrint printers only.
A printer your iPhone can’t see. If your printer never appears in the list, the app can’t print to it, and you won’t be asked to pay. Setting up a printer’s Wi-Fi is done on the printer or in its maker’s app.
Edge-to-edge prints on letter paper. Each 4 x 6 sits inside the printer’s margins, with white around it to trim.
Free prints of your own photos. The test page and the test photo are free; your own photos need Unlimited Printing.

For other sizes, the same steps work: wallet-size photos fit up to 8 on a letter sheet, 3.5 x 5 photos up to 4, and 5x7 photos two.

FAQ

Why does my iPhone print a 4x6 photo on the whole page?

Because the print screen in Photos has no size setting. iOS sizes the photo to the paper the printer reports, so on a letter sheet a 4x6 photo comes out filling most of the page. To get 4 x 6 inches, the photo has to be placed at that size first, in Pages or in a printing app.

How many 4x6 photos fit on a letter sheet?

Two. A letter sheet is 8.5 x 11 inches, so two 4 x 6 prints fit one above the other, each lying sideways, with room left for the printer’s margins. iPrint Printer puts them 3 mm apart so you can cut between them.

Can I print a 4x6 on letter paper without an app?

Yes, with Apple’s free Pages app: set the document to Letter, add the photo, and type its width and height under Format, then Arrange. It takes a few taps for every photo, and it’s worth measuring the first print with a ruler.

Does this work with HP, Canon, Epson and Brother printers?

iPrint Printer works with any of their printers that support AirPrint and sit on the same Wi-Fi as your iPhone or iPad. Apple says AirPrint is built into most popular printer models, but not every one has it. Print the free test page in iPrint Printer to check yours.
