Photo print sizes
Photo prints use inch-based R sizes: 4R is 4 × 6 in (101.6 × 152.4 mm), 5R is 5 × 7 in and 8R is 8 × 10 in. The 4R size matches the 3:2 shape of most camera sensors, and passport photos follow separate rules (35 × 45 mm in most countries, 2 × 2 in in the US).
From A3+ Super B (photo) (330.2 × 482.6 mm) to 2R (63.5 × 88.9 mm).

About this series
Photo sizes are a trade convention shared by minilabs, online printers and frame makers worldwide. They are inch-based even in metric countries, and most are named with an R (rectangular) number that gives the shorter side in inches.
4R (101.6 × 152.4 mm, 4 × 6 in) is the standard snapshot and the only common print with the same 3:2 proportion as 35 mm film and most digital camera sensors. 5R (127 × 177.8 mm, 5 × 7 in) is 5:7 and 8R (203.2 × 254 mm, 8 × 10 in) is 4:5, so both crop a little from a full frame. The S prefix marks the versions that keep 3:2: S8R is 8 × 12 in (203.2 × 304.8 mm) and S10R is 10 × 15 in. Larger sizes run through 11R (11 × 14 in), 16R (16 × 20 in) and 20R (20 × 24 in).
Japan uses its own names. L (89 × 127 mm) is the same as 3R, 2L (127 × 178 mm) is 5R and KG (102 × 152 mm) is 4R. Digital-era sizes such as LD/DSC (89 × 119 mm) and LW (89 × 133 mm) are cut to fit 4:3 and 3:2 sensors without cropping.
A3+ (330.2 × 482.6 mm, 13 × 19 in) is the largest sheet most desktop photo inkjets accept and is the same as Super B. Passport photos are separate: ICAO countries use 35 × 45 mm and the United States uses 2 × 2 in (50.8 × 50.8 mm). Wallet prints are 63.5 × 88.9 mm, the size of a playing card.
A practical tip: check the camera's aspect ratio before ordering. A 3:2 file prints edge to edge on 4R, 6R or S8R; on 5R or 8R the lab will crop about 7 to 17 percent of the long side, so keep important detail away from the ends.
Which size to order
4R is the album and shoebox size, and the one to order in bulk. 5R is the desk frame and the greetings card. 8R is the portrait size: school photographs, headshots and anything going on a wall in a frame you bought off a shelf. Above that, 11R and 16R are wall pieces that need a mount and a proper frame.
If you are printing from a phone rather than a camera, order 4R or ask for the S sizes. Phone photographs are usually 4:3, which crops harder than the 3:2 of a camera on every print size except the ones cut for it.
What gets cropped
A 3:2 file prints edge to edge on 4R, 6R and S8R. On 5R the lab trims roughly 7 percent off the long side, and on 8R roughly 17 percent. That is enough to remove a shoulder or the top of a head, and the lab will not ask first.
The fix is to leave room when you shoot or crop, not to argue with the lab afterwards. Keep anything you care about away from the short ends of the frame.
Resolution you need
At the 300 dpi labs assume, a 4R print needs 1,200 × 1,800 pixels, 5R needs 1,500 × 2,100 and 8R needs 2,400 × 3,000. Any modern phone clears 8R comfortably. What does not clear it is a photograph that has been sent through a messaging app, which may have been resized to a fraction of the original.
Always print from the original file. The pixel and DPI calculator will tell you the largest print a given file supports.
What drives the price
Print area is the obvious one, and it rises faster than the size name suggests: an 8R is four times the area of a 4R, not twice. Finish matters next, with lustre and metallic costing more than gloss. After that it is volume, since labs price in bands, and a bordered print sometimes costs less than borderless because it wastes less paper.
Questions about this series
What size is a 4R photo?
4R is 4 × 6 in (101.6 × 152.4 mm). It is the standard snapshot size and has the 3:2 proportion of 35 mm film and most camera sensors, so a full frame prints without cropping.
What are the standard photo print sizes?
What size is a passport photo?
35 × 45 mm in the UK, EU, Australia and most ICAO countries. The United States uses 2 × 2 in (50.8 × 50.8 mm). Both require the face to occupy a set proportion of the frame.
Is 8 × 10 the same shape as 4 × 6?
No. 4 × 6 is 3:2 and 8 × 10 is 4:5. Enlarging a 4 × 6 to 8 × 10 crops about 17 percent from the long side. For an uncropped enlargement use 8 × 12 in (S8R, 203.2 × 304.8 mm).
What size should I print my photos?
Will my photo get cropped?
Probably, unless the print shape matches the file shape. A 3:2 camera file fits 4R, 6R and S8R exactly. On 5R about 7 percent of the long side is trimmed, and on 8R about 17 percent. Phone photographs are usually 4:3 and crop more on every size.
What resolution do I need for an 8 × 10 print?
2,400 × 3,000 pixels at the 300 dpi labs assume. Any recent phone or camera exceeds that, but a photograph that has been sent through a messaging app may not.
Why does a bigger print cost so much more?
Price follows area, not the size name. An 8R is four times the area of a 4R, and larger sizes also use heavier paper and are handled individually rather than in a batch.
