Preparation method:
Print pixels use millimetres divided by 25.4 and multiplied by DPI; the head check compares percentage coverage.
pixels = round((millimetres / 25.4) × DPI)

Image Cropper Crop one image locally with exact aspect and pixel controls, then review upscaling and transparency along with quality or file-budget risks.
Image Resizer Resize one image locally, compare fit or crop geometry, and tune format quality against a file-size target before downloading.
Image Format Converter Convert one image locally with format, resize, crop, quality, and transparency controls while checking the actual output and byte size.
Country Information Lookup Find country or territory facts from names and common identifiers, then review ranked matches and source freshness from a frozen dataset.

A document photo is judged as a measured biometric image, not merely a small portrait. The application authority may specify the outside width and height, the distance from chin to crown, the background, pose, recency, print finish, file dimensions, and the submission route. A crop can match the outer rectangle and still fail because the face occupies the wrong share of the image.

The document and application channel must be chosen before resizing. Printed U.S. passport photos use a 51 by 51 mm square, while many European passport routes use a 35 by 45 mm portrait. Canada uses a 50 by 70 mm portrait, and its digital-renewal rules differ from its printed-photo rules. A generic “passport size” therefore has no reliable worldwide meaning.

MeasurementWhat it controlsCommon mistake
Outer size or aspect ratioThe final crop or printed cutoutStretching the face to force a different shape
Head height or face coverageHow much of the frame the applicant occupiesChecking only the outer dimensions
Pixel dimensionsThe raster size prepared for a chosen print resolution or upload ruleTreating DPI as proof of sharpness or acceptance
Sheet margin and gutterHow many cutouts fit without overlapping trim spaceLetting a printer rescale the finished sheet

Pixel dimensions are a preparation aid, not an approval. Dots per inch (DPI) converts a physical print size into a raster target, but it cannot restore detail to a blurred or compressed source. Background, lighting, expression, eyeglasses, editing, and current application instructions remain separate acceptance conditions.

Official requirements can change and may differ for adults, children, paper forms, digital renewal, visas, and overseas missions. The issuing authority makes the final decision, so the latest source for the exact document route should be checked before capture, printing, or upload.

How to Use This Tool:

Choose the authority route first; the physical size, head band, and digital requirements all follow that choice.

  1. Select the exact Country or document and choose a print, digital, or sheet output target.
  2. Set Print resolution between 150 and 600 DPI when preparing pixels for print. For a digital route, prefer the authority's published pixel range when one is available.
  3. Measure from the bottom of the chin to the crown and enter the value in millimetres, inches, or percent of photo height. Read Head fit to see whether the measurement is below, within, or above the selected band.
  4. For a print sheet, choose the paper size and add the required cut gutter and edge margin. Print the resulting layout at 100% scale.

Interpreting Results:

Within head band means the entered chin-to-crown measurement falls on or between the stored lower and upper limits. It does not assess centering, eye position, shadows, facial expression, image alteration, or file quality. A result at either boundary is included; values below the minimum or above the maximum are flagged.

Use the pixel result as a target canvas size for physical printing. When the selected authority publishes a separate digital minimum or maximum, that published range takes priority over a DPI-derived estimate. Sheet capacity is a geometric estimate only; confirm the printer's non-printable area and disable fit-to-page scaling.

Technical Details:

The calculation keeps physical measurements in millimetres. One international inch equals exactly 25.4 mm. A head measurement entered in inches is multiplied by 25.4, while a percentage is converted through the selected photo height. Unit changes preserve the same physical head size.

Formula Core:

Print pixels are the physical dimension divided by 25.4, multiplied by DPI, then rounded to the nearest whole pixel.

pixels=round(millimetres25.4×DPI)

Head coverage compares the measured chin-to-crown height with the full photo height. The result retains full precision for the comparison and is rounded only for display.

head coverage=measured head heightphoto height×100%

For a sheet, usable width and height subtract twice the edge margin. Columns and rows use floor division after adding one gutter to both the available span and cutout pitch. Capacity is columns multiplied by rows. Upright and rotated cutouts are both tested; rotation is selected only when it fits more copies, so ties remain upright.

columns=⌊sheet width−2margin+gutterphoto width+gutter⌋

The range table reflects the routes available in the lookup, not a universal standard. For Australia, pixel and sheet calculations deliberately use the minimum accepted 35 by 45 mm cutout. For the Netherlands, the stored head-height band applies to applicants aged 11 and older.

Accuracy Notes:

  • The result checks dimensions and the entered head measurement; it does not inspect an image or decide whether an authority will accept it.
  • Authority pages can change by document type, age, location, and application channel. Follow the source linked for the selected route.
  • DPI-derived pixels assume the file will be printed at the stated resolution and at 100% scale.
  • Sheet counts do not model printer bleed, lab-specific safe areas, or cutting tolerance beyond the entered gutter and margin.

Worked Examples:

U.S. passport print at 300 DPI

A 51 mm side becomes round(51 ÷ 25.4 × 300), or 602 pixels. A 31 mm head occupies about 60.78% of the photo height and remains within the 25 to 35 mm authority band.

Rotated sheet fit

A rectangular cutout is tested upright and rotated after margins and gutters are removed from the sheet. The reported orientation changes only when the rotated grid produces a larger whole-number capacity.
