The Department of Posts publishes the Gramin Dak Sevak upload rules in the India Post GDS Schedule-II July 2026 — Annexure-II (pp. 6–7). Unlike most recruitment notices, which state a size band and leave the shape to you, this one states a shape for each file as a ratio: “File size: 30 KB to 100 KB. Image dimensions: Recommended 320 × 400 pixels. Aspect Ratio: 4:5 (Width: Height)” for the photograph, and “File size: 20 KB to 100 KB. Image dimensions: Recommended 300 × 120 pixels. Aspect Ratio: 5:2 (Width : Height)” for the signature. Both files are JPG/JPEG.
What 4:5 and 5:2 mean in practice
A ratio written as width : height tells you how many times wider than tall the image is. The photograph’s 4:5 is 0.8 — a portrait, a little taller than it is wide. The recommended 320 × 400 pixels is exactly that shape at a modest size. The signature’s 5:2 is 2.5 — a long, low strip, 2.5 times as wide as it is tall, and again the recommended 300 × 120 pixels is exactly that shape.
Because the shape is stated, the tool above checks it. An exact ratio test would fail a correct crop that rounded by a single pixel, so it allows a narrow window either side — the photograph passes from 0.78 to 0.82, the signature from 2.44 to 2.56. That tolerance is MiniPx’s, not India Post’s; the notice states only the ratio itself.
Compression cannot fix a shape. If the tool reports that the ratio is out, crop the image to 4:5 for the photo or 5:2 for the signature, then compress. A passport-style photo cropped for another exam is often a slightly different portrait shape and can sit just outside the window, so re-crop it rather than assume it will pass.
The DPI line, explained
The notice also lists 72–150 DPI for both files. DPI is a number stored inside the image file that tells a printer how large to print it; it does not change how many pixels the image has or how much detail it carries. On an upload form, the pixel dimensions and the file size are what describe the image. A 320 × 400 pixels photo is the same picture whether its DPI tag says one thing or another. If a form ever complains about DPI specifically, that is a metadata question rather than a quality one.
Taking the GDS photograph
The notice’s guidance for the picture: plain white or light-coloured background, and the face occupies 70–80% of the image. It also says to avoid scanned photos and selfies. Treat that as a rule rather than a suggestion: do not upload a selfie or a scan of an old print. A fresh photo taken by someone else, straight on and at head-and-shoulders distance, is what the notice is steering you towards.
- Ask someone to take the photo from about a metre away, at your eye level, rather than holding the phone yourself.
- Frame head and shoulders with a little space above the head, then crop to 4:5; the face should fill most of the frame.
- If no plain wall is available, the passport photo maker will give you a white background; crop its result to 4:5 before compressing here.
Preparing the 5:2 signature
The signature should be written in black or blue pen on white paper, and the notice adds that the signature occupies 70–80% of the image. That second rule decides how you crop. Draw a light rectangle 5 units wide by 2 units tall around where you will sign, sign inside it so the signature spans most of the width, and crop to the rectangle. The result is the right shape, and the signature fills the frame as the notice asks.
A signature cropped tightly to the ink alone is usually far wider than 5:2 or far narrower, depending on how you sign — which is why cropping to a drawn rectangle beats cropping to the strokes.
Why GDS uploads get rejected
The wrong shape: a square photo, a landscape phone shot, or a signature strip cropped to the ink.
A face too small in the frame because the photo was taken from too far away.
A coloured or cluttered background.
A file under the floor. Both bands have a minimum, and a small, tightly compressed signature can go below it. The tool checks both ends.
