Resize a photo to 50×70 mm (591×827 pixels)
A 50×70 mm print at 300 DPI is 591×827 pixels. Set 50×70 mm and 300 DPI in the panel and choose crop to fill: a 4:3 phone photo loses 46.4% and still gives 1,097 pixels per inch. As a JPEG, a head-and-shoulders portrait comes to about 76.7 KB at the panel's default quality 85 and 57.3 KB at quality 75.

How 50×70 mm turns into pixels
An inch is exactly 25.4 mm, so at 300 DPI the pixel size is 50 mm ÷ 25.4 × 300 = 590.551, rounded to 591 px wide, and 70 mm ÷ 25.4 × 300 = 826.772, rounded to 827 px tall. 50×70 mm is a portrait shape with sides in the ratio 5:7 (0.7143 as a decimal), 1.97×2.76 in in the other unit.
The same 50×70 mm needs 394×551 px at 200 DPI and 1181×1654 px (1.95 MP) at 600 DPI. PixelFit writes the DPI you set into the JPEG header (the JFIF density field), so print software that reads it knows the file is meant to come out at 50×70 mm.
Where 50×70 mm is asked for
Each line comes from the official notice listed under Sources, checked October 2026. Rules change: verify with the notice before you submit.
- Canadian passport photos: 50 mm wide by 70 mm high. The face, chin to crown, must measure 31 mm to 36 mm.
- At 300 DPI that face height of 31 to 36 mm is 366 to 425 px of the 827 px frame (44.3% to 51.4% of the height).
Is your photo sharp enough for 50×70 mm?
After the crop to fill, this is how many source pixels land on each inch of 50×70 mm. Above 300 DPI the picture is reduced to 300 DPI; below it, PixelFit has to enlarge the crop and fine detail softens.
| Starting image | Crop to fill keeps | Area lost | Pixels per inch at 50×70 mm | To reach 300 DPI |
|---|---|---|---|---|
| 12 MP phone photo (4032×3024, 4:3) | 2161×3024 (left and right cut) | 46.4% | 1,097 DPI | reduced (0.27×) |
| 24 MP camera photo (6000×4000, 3:2) | 2859×4000 (left and right cut) | 52.4% | 1,451 DPI | reduced (0.21×) |
| Full HD screenshot (1920×1080, 16:9) | 772×1080 (left and right cut) | 59.8% | 392 DPI | reduced (0.77×) |
| Vertical phone video frame (1080×1920, 9:16) | 1080×1511 (top and bottom cut) | 21.3% | 548 DPI | reduced (0.55×) |
50×70 mm in pixels at each print resolution
Pixels = millimetres ÷ 25.4 × DPI. The panel uses 300 DPI unless you change it; the file sizes are for a portrait saved as JPEG.

| 150 DPI | 295×413 | 0.12 MP | ≈ 20.3 KB | ≈ 32.6 KB |
| 200 DPI | 394×551 | 0.22 MP | ≈ 31 KB | ≈ 50.7 KB |

Will a 50×70 mm photo fit a KB limit?
Saved at 300 DPI (591×827 px), a head-and-shoulders portrait of 50×70 mm comes to about 44.2 KB at JPEG quality 60, 57.3 KB at 75 and 96.1 KB at 90, and about 32.2 KB as WebP at 75. Dropping to 200 DPI (394×551 px) brings quality 75 down to about 31 KB, but the print then holds fewer pixels per inch.
At 300 DPI the photo does not fit under 20 KB even at quality 30; it fits under 50 KB up to quality 65 and under 100 KB up to quality 90; under 200 KB it fits even at quality 95. Set the KB limit next to the size and PixelFit picks the highest quality that fits.
Printing 50×70 mm copies
Without margins or cutting gaps, 4 copies fit on one 4×6 in (102×152 mm) photo print, 16 on an A4 sheet, 15 on US Letter (some turned sideways where that packs more). Print at 100% scale, never "fit to page", or a small ID photo of 50×70 mm comes out the wrong size; 591×827 px at 300 DPI is exact.
Sizes close to 50×70 mm

How to resize a picture to 50×70 mm
-
Add the picture
Drop, paste or pick the photo in the PixelFit panel at the top of this page; it is decoded in your browser and never uploaded.
-
Set the size
Pick mm as the unit, enter 50×70 mm and 300 DPI; the tool turns that into 591×827 pixels.
-
Choose how it fits
Choose crop to fill to keep the 5:7 frame without stretching (a phone photo loses 46.4%, left and right cut). Fit inside keeps the whole picture as a 591×443 file instead; Pad with colour puts that on a full 591×827 canvas.
-
Pick the format and download
Keep JPG (without a KB limit PixelFit saves at quality 85, about 76.7 KB for a head-and-shoulders portrait) so the 300 DPI stamp travels with the file, or choose PDF to get the picture as a PDF page, then download.
