Picking the wrong photo size is one of the fastest ways to get a passport or ID photo rejected — or to print a sheet where every copy is a few millimeters off. This chart lists the sizes we use in Just ID Photo and the free Photo Sheet Maker, based on official specs where they exist and mainstream 办证惯例 for common China “inch” sizes.
Always double-check your form or authority before you print. Rules for expression, glasses, and head height can change even when the outer crop stays the same.
Quick chart (core sizes)
| Document / size name | Size (mm) | Notes |
|---|---|---|
| US Passport / Visa | 51 × 51 | Same as 2×2 in. Covers non-immigrant and immigrant visa photo size. |
| UK Passport / Visa | 35 × 45 | Also used for many UK applications. |
| EU / Schengen | 35 × 45 | Common EU passport & Schengen photo size. |
| Canada Visa | 35 × 45 | Frame at least 35×45 mm per common guidance. |
| Australia Visa | 35 × 45 | Same outer size as UK/EU in many layouts. |
| Chinese Passport | 33 × 48 | Official passport crop. |
| China 1 Inch (一寸) | 25 × 35 | Everyday ID / resume photo convention. |

| China Small 2 Inch (小二寸) | 35 × 45 | Same mm as UK/EU crop. |
| Chinese ID Card (2nd gen) | 26 × 32 | Use this — not the old 22×32 “ID card” listing. |
| Driver’s license (China convention) | 22 × 32 | Common办证 size; confirm with your bureau. |

Four size mistakes worth fixing
Many free “photo type” lists copy older data. These four corrections matter in real printing:
| Item | Wrong (common) | Correct |
|---|---|---|
| US Immigrant Visa | 35 × 40 mm | 51 × 51 mm (same as US passport / non-immigrant visa) |
| Chinese ID Card | 22 × 32 mm | 26 × 32 mm (2nd-generation standard) |
| China 2 Inch | 38 × 51 mm | 35 × 49 mm |
| China Large 2 Inch | 35 × 50 mm | 35 × 53 mm |
If a tool still offers US Immigrant Visa at 35×40, treat it as outdated. If it lists both “Chinese ID Card 22×32” and “2nd gen 26×32”, keep 26×32 only.
Color vs black & white is not a size
Lists that split Large 1 Inch (Color) / (B&W) as separate dimensions are usually wrong:
- White / blue / red backgrounds are a background choice, not a new mm size.
- 40 × 55 and 27 × 38 “color inch” variants are best treated as custom / extended sizes — not standard 大一寸 / 小一寸.
- An optional 2 Inch alt (38 × 51) exists for older shop habits; prefer 35 × 49 unless a specific office asks for 38×51.
How these sizes show up in Just ID Photo
- Homepage maker — curated high-demand documents (US, UK/EU, Canada, Australia, China passport / inch / ID card / 2-inch, Japan, HK SAR, Schengen-from-US).
- Photo Sheet Maker — the clean chart above plus a few custom options for non-standard shops.
- 4×6 print sheet — photos stay in official orientation; only the paper may rotate so more copies fit (same idea as classic sandphoto-style layout).
Paper naming (4R / 5R / Letter / A4) is a separate decision — see photo paper sizes explained.
Print tips that keep millimeters honest
- Export at 300 DPI, then print at 100% / actual size.
- Turn off fit to page and kiosk auto-crop.
- Match paper in the layout to the physical stock (4×6 / 4R at most US drugstores).
- Cut along the guides; don’t scale the JPEG in Preview or Photos before printing.

FAQ
Is US immigrant visa photo still 35×40?
No for the outer size we ship: use 51 × 51 mm (2×2 in), same as US passport / non-immigrant visa. Always follow the specific form you are filing.
Is Chinese passport the same as 大一寸?
Outer size yes — both 33 × 48 mm. Requirements for expression, recentness, and background can still differ by use case.
Which China size should I pick for a generic “证件照”?
If the office only says “一寸”, start with 25 × 35. If it says “二寸”, use 35 × 49. If it says “身份证”, use 26 × 32.
Can I put 35×45 photos on a 4×6 sheet?
Yes. Choose UK / EU / Small 2 Inch (35×45) and paper 4×6 (4R) in the sheet maker.
