Photo size · 33×48 mm

The 33×48 mm photo — China's visa size, in inches, pixels, and both orders.

33 × 48 mm — 33 millimeters wide, 48 millimeters tall — is the printed photo size for a China visa. You will see it written both ways: official charts put the height first, 48 × 33 mm, while most people type the width first, 33x48. Same photo either way. In inches it is roughly 1.30 × 1.89 — a narrow portrait, not the square 2 × 2 inch US photo and not the 35 × 45 mm UK/Schengen frame it gets mistaken for. And the print size is only half the spec: the COVA online application takes a separate digital upload with its own pixel and kilobyte window, which is where most photos actually get stuck.

33x48 or 48x33

Is it 33x48 or 48x33? Both — here is why.

The two numbers name one photo. The frame is 33 mm wide and 48 mm high, and the only thing that changes between "33x48" and "48x33" is which side gets said first. Size charts — including ours — often write it height first, as 48 × 33 mm (h × w), because that is how the spec sheet presents it. Search boxes and photo-lab order forms usually go width first. If you are double-checking which side is which: the photo is taller than it is wide, so 48 is the height, always.

Inside that frame, the printed spec also fixes the head: 28–33 mm of head height in the 48 mm frame. That band, not the frame itself, is what photos fail on — any print shop can cut a 33 × 48 rectangle, but no scissors move the head inside it.

The conversions

33x48 mm to inches and pixels

In inches: about 1.30 × 1.89 in — divide each side by 25.4 (33 ÷ 25.4 = 1.299, 48 ÷ 25.4 = 1.890). There is no tidy fraction, and it is not 2 × 2 inches, which is a different, square photo. In pixels there is no single answer, because millimeters only become pixels through a print resolution:

150 DPI195 × 283 px
300 DPI390 × 567 px
600 DPI780 × 1134 px

Each row is the same arithmetic: millimeters divided by 25.4, times the DPI, rounded — at 300 DPI, 33 ÷ 25.4 × 300 ≈ 390 and 48 ÷ 25.4 × 300 ≈ 567. The aspect ratio is 11:16 in every case. But before you convert anything, read the next section: the COVA upload publishes its own pixel figures, and they are not on this table.

Print vs digital

The COVA upload is a different spec — not a conversion

The 33 × 48 mm figure governs paper. The COVA portal upload has its own published window, read here straight from the spec we process against:

Photo size354×472 to 420×560 pixels
File size40–120 KB
FormatJPEG
Head height58.4–68.7% of the photo's height
Head tilt20° or less
BackgroundPlain white

Two things the numbers alone tell you. First, the upload window is not a DPI conversion of the print size — no row of the DPI table above lands inside it. Second, the shapes differ: 33:48 reduces to 11:16 (about 0.69), while 354:472 and 420:560 both reduce to exactly 3:4 (0.75). So scaling a scan of the print cannot hit the portal window — the photo has to be recropped to the digital frame, not resized. The head band carries over in spirit, though: 28–33 mm of a 48 mm print is the same roughly 58–69% band the digital spec states in percent.

If the portal already turned your file away, the fix is usually the file, not the face — walk through COVA photo upload failed. Full rulebook for the document: China visa photo requirements.

Close, but different

The sizes 33x48 is not

Two neighbors get mixed up with this one constantly. For the record:

  • 35 × 45 mm — the UK, Schengen and much of Asia. Two millimeters wider and three shorter than the China frame, which is exactly why it is a trap: it looks right at arm's length and fails on measurement. The 35x45 mm photo page covers who uses that one.
  • 2 × 2 in (51 × 51 mm) — the US passport and visa square. Different shape entirely; a photo composed for one cannot be trimmed into the other.

Every country's frame, digital window, and recency rule in one place: the passport photo size chart.

Getting one that passes

Getting a China visa photo that passes

The frame is the easy part — any editor can crop to 11:16 or 3:4. Rejections come from everything attached to the frame: the head band, the tilt limit, the pure-white background, and the upload's narrow kilobyte window, which ordinary photo files miss in both directions.

That is the work the maker buys you out of. You upload one plain photo and processing runs server-side: the background is replaced with pure white, the crop is solved so your head lands inside the 58.4–68.7% of the photo's height band, and the file comes back as 354×472 to 420×560 JPEG · 40–120 KB · pure white background — the digital file the COVA upload takes. This flow is digital-only: the portal takes a file, not paper, so there is no print sheet.

Questions

Fair questions, straight answers.

Is the China visa photo 33x48 or 48x33?

Both describe the same photo. It is 33 mm wide and 48 mm tall — a portrait rectangle. Official charts often write it height first, as 48 × 33 mm (h × w), while most people type the width first, 33x48. Whichever order you saw, there is one frame: taller than it is wide, 33 by 48.

Can I use a 35x45 mm photo for a China visa?

No. 35 × 45 mm is the UK/Schengen frame; the China visa print size is 33 × 48 mm — narrower and taller, with its own head-height band of 28–33 mm. The two are close enough to be a trap: a 35 × 45 photo needs recropping to the China spec, not trimming 2 mm off the sides.

What pixel size does the COVA upload need?

The portal upload window is 354 × 472 to 420 × 560 pixels, as a JPEG between 40 and 120 KB, on a plain white background. Those numbers are not a DPI conversion of the 33 × 48 mm print — the upload is its own spec, and the file has to land inside the pixel and kilobyte window to go through.

What is 33x48 mm in inches?

About 1.30 × 1.89 inches — 33 and 48 divided by 25.4. There is no clean fraction, and it is not the 2 × 2 inch (51 × 51 mm) square the US uses. If a form asks for 2 × 2, that is a different photo, not a conversion of this one.

Do I need a printed photo or a digital file for a China visa?

The official spec publishes both: a printed photo of 48 × 33 mm (height by width) with the head 28–33 mm, and a separate COVA portal upload of 354 × 472 to 420 × 560 px at 40–120 KB. Our China flow produces the digital file, because that is what the COVA upload takes — it is digital-only, with no print sheet.
