NBEMS photo and signature size

The NBEMS form takes a photo file of at most 80 KB and a signature of about 35 × 15 mm, at most 80 KB, both as JPG/JPEG. It also takes a left thumb impression (at most 80 KB).

NBEMS photo

JPG · under 80 KB (at most 80,000 bytes) · original pixel size · white background

PixelFit aims at 80,000 bytes or less, so the file passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

NBEMS upload specifications

Values for the NBEMS online application image upload, copied from NBEMS Image Upload Instructions, checked 31 October 2026; "not stated" means the source gives no figure for it.

Upload	Pixel size	Print size	File size	Format	Background
Photo	not stated	not stated	at most 80 KB	JPG/JPEG	white
Signature	276 × 118 px at 200 DPI (computed; the tool uses this)	35 × 15 mm at 200 DPI	at most 80 KB	JPG/JPEG	blank white paper without lines

NBEMS sizes in pixels and millimetres

Print sizes become pixels at a resolution (pixels = mm ÷ 25.4 × DPI); pixel sizes become print sizes the other way round. Computed for the NBEMS uploads at 200 and 300 DPI.

Upload	Aspect ratio	Megapixels	At 200 DPI	At 300 DPI
Signature	7:3 (print size)	0.07 MP at 300 DPI	276 × 118 px	413 × 177 px
Left thumb impression	7:3 (print size)	0.07 MP at 300 DPI	276 × 118 px	413 × 177 px

What the NBEMS KB limits mean in bytes

The NBEMS photo limit of 80 KB is 81,920 bytes when 1 KB = 1,024 bytes and 80,000 bytes when 1 KB = 1,000 bytes; a file of 80,000 bytes or less passes either way.

The NBEMS signature limit of 80 KB is 81,920 bytes when 1 KB = 1,024 bytes and 80,000 bytes when 1 KB = 1,000 bytes; a file of 80,000 bytes or less passes either way.

The NBEMS left thumb impression limit of 80 KB is 81,920 bytes when 1 KB = 1,024 bytes and 80,000 bytes when 1 KB = 1,000 bytes; a file of 80,000 bytes or less passes either way.

Estimated JPG file size for NBEMS uploads

Estimated from sizes measured with sharp 0.35.5 / libvips 8.18.7 on public-domain sample images (31 October 2026), interpolated to each target size. Your own scan can land 30-50% either side, which is why the tool measures the real file.

Upload	Pixel size used	Quality 60	Quality 75	Quality 85	Quality 95	Limit
Signature	276 × 118 px	2.4 KB	3.4 KB	4.9 KB	9.2 KB	at most 80 KB
Left thumb impression	276 × 118 px	2.4 KB	3.4 KB	4.9 KB	9.2 KB	at most 80 KB

Will the NBEMS signature fit the limit?

For the NBEMS signature at 276 × 118 px (35 × 15 mm at 200 DPI), even quality 95, the highest setting estimated here, stays under 80 KB at about 9.2 KB.

For the NBEMS left thumb impression at 276 × 118 px (35 × 15 mm at 200 DPI), even quality 95, the highest setting estimated here, stays under 80 KB at about 9.2 KB.

Signature: The NBEMS signature file is no larger than 80 KB (80,000 bytes is safe under both KB definitions).

NBEMS compared with similar forms

Of these 5 forms, the NBEMS photo limit of 80 KB is number 4 of 5 from the strictest; a file made for a stricter form usually passes a more generous one only if it also meets the minimum and the pixel size.
