Dimensions

  • Print size: 40 x 60 mm (4 x 6 cm)
  • Pixel size: 472 x 709 px at 300 DPI (945 x 1417 px at 600 DPI)
  • DPI: 300-600 DPI; some official VFS pages cite a 1200 DPI minimum for print masters
  • Minimum digital dimension on the official VFS portal: 500 x 352 px (uploads below this fail validation)
  • File format / max file size: JPG, JPEG, or PNG; max 120 KB
  • Borders: none (borderless)
  • Color mode: color only

Head position

  • Face height: ~75% of photo height
  • Distance from top of photo to top of hair: ~10% of photo height (~6 mm)
  • Orientation: full frontal view; head and shoulders centered

Background

  • Color: white
  • Plain, solid; no patterns or shadows

Expression

  • Neutral expression, mouth closed
  • Eyes open, looking directly at camera
  • Hair must not cover facial features

Accessories

  • Glasses: not permitted (consistent with passport rule)
  • Head coverings: only for documented religious reasons; must not obscure face

Other rules

  • Recency: taken within the last 6 months
  • No filters, retouching, or digital alterations
  • Quantity: 1 photo required for VOA / e-VOA

Notes

  • The VFS e-VOA upload portal enforces a minimum 500 x 352 px dimension; submissions smaller than this are rejected client-side. The 472 x 709 px (300 DPI) target in the code spec satisfies the minimum on the long edge while preserving the 4 x 6 cm aspect ratio.
  • 4 x 6 cm is not the same as the embassy/consulate visa size (35 x 45 mm). Travelers using VOA cannot reuse a th_visa print.
  • Some sources cite 1200 DPI for print masters; this is rarely needed for the digital submission and conflicts with the 120 KB upload ceiling.

Sources

Can I wear glasses in my Thai VOA photo?

No — the VFS e-VOA portal does not permit glasses. This is stricter than the embassy/consulate visa spec, which tolerates glare-free prescription frames.

Can I wear a head covering for the VOA photo?

Only for documented religious reasons, and the covering must not obscure your face.

Can I smile in a Thai VOA / e-VOA photo?

No — neutral expression with mouth closed, eyes open and looking at the camera. Hair must not cover facial features.

How recent does the VOA photo need to be?

Within the last six months. No filters, retouching, or digital alterations are permitted; one photo is required.

What size does the Thai VOA portal require?

Print size 40 × 60 mm (4 × 6 cm); pixel target 472 × 709 px at 300 DPI. The VFS e-VOA upload portal enforces a **minimum 500 × 352 px** dimension — submissions below that are rejected client-side. Format JPG, JPEG, or PNG up to **120 KB**, white background, color only. Note: 4 × 6 cm is **not** the same as the embassy visa (35 × 45 mm) — a `th_visa` print cannot be reused here.

The same checks the authority will run — before you submit.

  • Face height & eye line measured from the pupil midpoint with sub-pixel accuracy, clamped to the tolerance range your authority publishes.
  • Background colour checked across a sampled grid — catches gradients and fringe from poor segmentation (ΔE < 3 against spec).
  • File-size ceiling enforced per-spec — recompressed silently for sub-60 KB e-visa portals, lossless for print.
  • Sharpness & expression guards warn on blur, closed eyes, or non-neutral expressions before you export.
