How to make a passport photo at home

Intermediate8 minutesUpdated

Quick answer

Choose the Crop tool, set Ratio to Custom with W 35 and H 45, frame the head and shoulders and press Enter or ↩. Then choose Image then Image Size…, set the units to Millimeters, Resolution to 300 and Width to 35: the photo becomes 413 × 531 pixels, exactly 35 × 45 mm in print. To print several, lay out eight on a 6 × 4 in sheet with a small margin, and print it at 100%.

A passport photo has to be an exact physical size, such as 35 × 45 mm, so two numbers matter: the shape of the crop and the resolution, how many pixels go into each inch of paper. At 300 pixels per inch (ppi), a common print standard, 35 mm needs 413 pixels and 45 mm needs 531.

In this tutorial you crop a phone photo to 35 × 45 mm, check the head size, and lay out eight copies on a 6 × 4 in print with room to cut.

Make a passport photo in six steps

  1. Open the photo

    Go to lilcactus.app and choose File then Open…, or drag the photo onto the window. To follow along exactly, open the sample photo from this page.

  2. Crop to 35 × 45 mm

    Right-click the crop button in the toolbar (or press and hold it) and choose Crop. On the options bar, set Ratio to Custom, type 35 for W and 45 for H, and tick Delete cropped pixels, so the cut-off parts don’t travel with the photo later.

    Drag a frame over the photo with the face in the middle, leaving room above the hair. In the sample the frame starts at the top edge of the photo, so the top of the hair sits about an eighth of the way down, and the chin about a sixth of the way up from the bottom edge. Drag inside the frame to move it, or drag a corner to resize it; the 35 : 45 shape is kept. Press Enter or ↩ to crop.

    The start of the Crop options bar: the Crop tool, Ratio Custom, W 35 and H 45, with Ratio, W and H ringed

    Further along the Crop options bar: Show Always, Shade 60% and Delete cropped pixels ticked and ringed
    Tick Delete cropped pixels.

  3. Set the print size and check the head

    Choose Image then Image Size… Keep Resample ticked. Set Units next to Width to Millimeters, type 300 for Resolution and press Tab, then type 35 for Width and press Tab. The height follows at 45 mm and the summary reads 413 × 531 px. Choose Bicubic Sharper and click Resize.

    Each country sets how tall the head should be. In the UK it is 29 to 34 mm from the chin to the crown; for a US 2 × 2 in photo, 1 to 1 3/8 in (25 to 35 mm) from the chin to the top of the head. Rules differ on whether hair counts, so check your own country’s rules.

    To measure it, press M (or right-click the selection button and choose Marquee Select) and drag a rectangle from the top of the hair to the bottom of the chin: the status bar shows its size. At 300 ppi, 11.8 pixels make 1 mm, so the sample’s 376 px is about 32 mm, inside both example ranges. Choose Select then Deselect afterward.

    The Image Size settings: 609 × 783 → 413 × 531 px, Width 35 and Height 45 in Millimeters, Resolution 300 pixels per inch, Resample ticked with Bicubic Sharper; Width, Units and Resolution ringed
    35 × 45 mm at 300 ppi: 413 × 531 pixels.

    Selection 376 px tall: about 32 mm at 300 ppi.
  4. Start the sheet and copy the photo onto it

    A 6 × 4 in print at 300 ppi is 1800 × 1200 px. You lay the photos out on a slightly smaller sheet first and add a white margin at the end, so no photo touches the edge of the paper. Choose File then New…, set Units to Pixels, type 1740 for Width, 1140 for Height and 300 for Resolution, and click Create.

    Click the photo’s tab above the canvas, choose Layer then Duplicate Into Other Document, then click the Untitled tab. The photo is on the sheet, in its top-left corner, as a layer called Background (copy). The copy goes to the leftmost other tab, so close any other documents first.

    With the photo’s tab active, this copies the photo to the sheet.
  5. Fill the top row

    Choose Layer then Duplicate Layer, then Layer then Align then Right Edges: with one layer selected, Align lines it up with the edge of the sheet, so the copy moves to the top-right corner. Choose Layer then Duplicate Layer twice more, for four photos in all.

    In the Layers panel, click the top photo row and Shift or ⇧-click the lowest one, just above Background, to select all four. Choose Layer then Distribute then Horizontal Spacing: the four photos spread out evenly across the top. Then click the top photo row on its own and choose Layer then Merge Down three times, so the row becomes one layer.

  6. Add the second row and the margin, then export

    Choose Layer then Duplicate Layer, then Layer then Align then Bottom Edges: the copy of the row drops to the bottom, giving eight photos. Choose Image then Canvas Size…, type 1800 and 1200, keep the center Anchor and click Resize: a 30 px border (about 2.5 mm) is added all around. It is transparent in the editor and turns white in a JPEG.

    Choose File then Export then JPEG… and click Export. Order a 6 × 4 in (also called 4 × 6) print from a photo lab, or print it at 100% (actual size), not “fit to page”, on 6 × 4 in photo paper. Then cut along the white gaps.

    The Canvas Size settings: Width 1800 and Height 1200 px, the center anchor chosen, Old 1740 × 1140 px and New 1800 × 1200 px
    Canvas Size 1800 × 1200 from the center.

For an online application

Online forms usually state their own pixel size. Export straight after the crop in step 2, before step 3 changes the size: choose File then Export then JPEG…, tick Resize output to meet an exact size, and click Export. If the form’s size has a different shape, crop with that W : H ratio instead; if it asks for more pixels than your crop has, start from a larger photo, because enlarging adds no detail.

Other sizes

Use the same steps with the ratio and size your rules ask for. At 300 ppi:

Photo sizeCrop ratio (W : H)Pixels at 300 ppi
35 × 45 mm35 : 45413 × 531
2 × 2 in (51 × 51 mm)1 : 1600 × 600
50 × 70 mm50 : 70591 × 827
33 × 48 mm33 : 48390 × 567

For 2 × 2 in photos, set Units to Inches and Width to 2 in step 3. Six of them fill a 6 × 4 in sheet edge to edge, with no room to cut, so use a 7 × 5 in print: make the sheet 2040 × 1440 px in step 4, use three photos across (two duplicates and Merge Down twice in step 5), and set Image then Canvas Size… to 2100 × 1500 px in step 6.

Check the photo against the rules

  • Head size: measure it as in step 3. If it is too big or small for your rules, choose Edit then Undo until the photo is back to its full size (four times after measuring: Deselect, the selection, Image Size and the crop) and draw the frame larger or smaller.
  • Background: most rules ask for a plain, light background without shadows. The sample’s wall has a soft shadow on the right; standing a step away from the wall, with the light in front of you, avoids it.
  • Edits: rules usually forbid retouching or changing the face. Some, such as the UK’s for printed photos, also say the photo must not be cut down from a larger picture, so check yours.

Fix common problems

The sheet shows the whole uncropped photo

Delete cropped pixels was unticked, so the hidden parts came along. Close the sheet, undo the crop and image size in the photo, tick the box, and crop again.

Duplicate Into Other Document is grayed out

Only one document is open. Create the sheet first (step 4), then click the photo’s tab.

The print comes out the wrong size

The printer scaled it to fit the paper. Print the exported JPEG at 100% (actual size), or let a photo lab print it as 6 × 4 in. File then Print… in Lil Cactus ignores the 300 ppi setting and scales the picture to the page width, so don’t use it for passport photos.

Passport photos: questions and answers

What resolution should a passport photo be?

Usually 300 pixels per inch for printing: a 35 × 45 mm photo is then 413 × 531 pixels. In Lil Cactus, set it in Image › Image Size… with Units Millimeters and Resolution 300.

Can I make a passport photo with my phone?

Yes, if the photo meets your country’s rules: facing the camera, even light, a plain light background. In Lil Cactus, crop and size it as on this page, then export the JPEG.

How many passport photos fit on a 6 × 4 print?

Eight photos of 35 × 45 mm, with room to cut between them. In Lil Cactus, lay them out as on this page. Six 2 × 2 in photos fill the sheet edge to edge, so use a 7 × 5 in print for those.

Will my passport photo be accepted?

Not necessarily: that depends on your country’s rules, which Lil Cactus doesn’t check. Compare the photo with the official requirements for size, head height, background and expression before you submit it.

Is my photo uploaded when I make a passport photo in Lil Cactus?

No. Everything runs in your browser, on your own device. When statistics are on, the editor records which tools are used, never the image, as the privacy policy explains.
