Most bank and SSC forms want a 10\u201320 KB signature, so the file sitting in your phone from your last form is usually too small for the RRB NTPC signature size rule. This guide covers the full RRB NTPC photo and signature size rules and shows you how to fix that in about two minutes with free tools, how to shrink a file that is too big, and how to pass the live photo step on the first try.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Last date (Graduate, CEN 06\/2026): 6 November 2026, 11:59 PM.<\/strong> Fee payment closes on 8 November, and the modification window runs from 9 to 18 November 2026.

Once you understand them, getting the file right becomes simple.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"file-size-30-49-kb\">RRB NTPC signature size: why 30 KB to 49 KB?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The board wants a signature that is clear enough to compare with your handwriting at every later stage. A file under 30 KB is usually too small or too blurry for that, and a file over 49 KB slows the portal down. So the RRB NTPC signature size sits in a narrow band. Treat 49 KB as a hard wall: a file at 49.6 KB shows as &#8220;50 KB&#8221; on many phones and can still be rejected.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"signature-dpi-and-pixels\">RRB NTPC signature size in pixels and DPI, explained simply<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pixels are the tiny dots that make up your image. A 140 \u00d7 60 px image has 140 dots across and 60 dots down. That is the <em>minimum<\/em>, so a bigger image such as 600 \u00d7 340 px is allowed and is usually better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DPI means dots per inch. It tells you how many pixels were captured for each inch of paper. The notice asks for a scan of at least 100 DPI. A 35 mm wide box is about 1.38 inches, so at 100 DPI it becomes about 138 pixels wide. That is why the minimum width in the RRB NTPC signature size rules is 140 px. A modern phone camera captures far more than 100 DPI, so a clear phone photo of your signature meets this rule easily.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Term<\/th><th>Simple meaning<\/th><th>What to do<\/th><\/tr><\/thead><tbody><tr><td>Pixels (px)<\/td><td>Number of dots in the image<\/td><td>Keep at least 140 \u00d7 60; about 600 \u00d7 340 is ideal<\/td><\/tr><tr><td>DPI<\/td><td>Dots captured per inch of paper<\/td><td>At least 100 DPI; any clear phone photo or scan is fine<\/td><\/tr><tr><td>KB<\/td><td>Space the file takes<\/td><td>Between 30 KB and 49 KB<\/td><\/tr><tr><td>JPG \/ JPEG<\/td><td>Image format<\/td><td>Export as .jpg, not PNG, HEIC or PDF<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"box-ink-and-handwriting\">The 35 \u00d7 20 mm box, black ink and running handwriting<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Draw a light 35 mm \u00d7 20 mm box on white paper if it helps, sign inside it, then crop just outside the box so the signature sits in the centre. The box is part of the RRB NTPC signature size rules because it fixes the shape of the image. Use a black ball pen or gel pen. Sign in your normal running (joined) handwriting. Capital letters or separate block letters are not accepted as a signature.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-signature-gets-rejected\">Why your signature keeps getting rejected<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A signature is mostly white paper, and white compresses extremely well. So a 140 \u00d7 60 pixel JPG of your signature is often only 5\u201312 KB, well below the 30 KB minimum RRB NTPC signature size. Moving the quality slider to 100% won&#8217;t save you if the image has too few pixels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The fix is to make the image bigger while keeping the same shape. A size of around <strong>600 \u00d7 340 pixels<\/strong> keeps the shape of the 35 mm \u00d7 20 mm box and usually lands comfortably in the 30\u201349 KB range. If you have the opposite problem, a raw phone photo of 2\u20134 MB, you first resize it and then lower the quality until it fits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"make-signature-in-7-steps\">RRB NTPC signature size in 7 easy steps (free, on your phone)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Follow these steps to get the exact RRB NTPC signature size without installing any app.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n\n<li><strong>Sign on plain white paper<\/strong> with a black pen, in your normal running handwriting. Sign a little bigger than usual so the strokes stay sharp.<\/li>\n\n\n<li><strong>Take a photo<\/strong> in daylight, holding the phone straight above the paper so there&#8217;s no shadow.<\/li>\n\n\n<li><strong>Crop tightly<\/strong> around the signature with the <a href=\"https:\/\/toolscrush.com\/tools\/crop-image\">Crop Image tool<\/a>. Leave a small white margin on all sides.<\/li>\n\n\n<li><strong>Resize to about 600 \u00d7 340 px<\/strong> with the <a href=\"https:\/\/toolscrush.com\/tools\/image-resizer\">Image Resizer<\/a>. Choose JPG as the export format and download.<\/li>\n\n\n<li><strong>Set the file size<\/strong> in the <a href=\"https:\/\/toolscrush.com\/tools\/image-compressor\">Image Compressor<\/a>. Move the quality slider and watch the &#8220;Compressed Size&#8221; figure until it reads 40\u201345 KB, then download.<\/li>\n\n\n<li><strong>Check the file details.<\/strong> Open the file&#8217;s details on your phone and confirm it&#8217;s a .jpg within the RRB NTPC signature size of 30\u201349 KB.<\/li>\n\n\n<li><strong>Upload and preview.<\/strong> Upload it on the form, zoom in on the preview, and confirm every stroke is dark and clear before you move on.<\/li>\n\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Everything runs inside your browser, so your signature never leaves your phone. Once the file meets the RRB NTPC signature size, rename it to something simple such as <em>signature.jpg<\/em> so you can find it again before DV.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"increase-or-reduce-signature-kb\">Increase 12 KB to 30 KB or reduce 80 KB to 49 KB<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">These are the two problems we see most often with the RRB NTPC signature size. Pick the one that matches your file.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"increase-12-kb-to-30-kb\">How to increase a 12 KB signature to 30 KB<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n\n<li>Open your 12 KB file in the <a href=\"https:\/\/toolscrush.com\/tools\/image-resizer\">Image Resizer<\/a>.<\/li>\n\n\n<li>Increase the size to about 600 \u00d7 340 px. Keep the aspect ratio locked so the signature doesn&#8217;t stretch.<\/li>\n\n\n<li>Export as JPG at high quality and check the size.<\/li>\n\n\n<li>If it&#8217;s still under 30 KB, resize again to about 800 \u00d7 457 px and export once more.<\/li>\n\n\n<li>Use the <a href=\"https:\/\/toolscrush.com\/tools\/image-compressor\">Image Compressor<\/a> only to bring the final file into the 40\u201345 KB band if it overshoots.<\/li>\n\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Increasing pixels from an already tiny image can make the edges soft. If the result looks blurry, it is faster to sign again on fresh paper and start from a new phone photo.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"reduce-80-kb-to-49-kb\">How to reduce an 80 KB signature to 49 KB<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n\n<li>Open the 80 KB file in the <a href=\"https:\/\/toolscrush.com\/tools\/image-compressor\">Image Compressor<\/a>.<\/li>\n\n\n<li>Lower the quality slider in small steps and watch the size figure.<\/li>\n\n\n<li>Stop when it reads 40\u201345 KB, the safest part of the RRB NTPC signature size range. Do not go all the way down to 30 KB, which can blur the strokes.<\/li>\n\n\n<li>If quality has to drop too low, first reduce the dimensions to about 600 \u00d7 340 px in the <a href=\"https:\/\/toolscrush.com\/tools\/image-resizer\">Image Resizer<\/a>, then compress.<\/li>\n\n\n<li>Confirm the width and height are still at least 140 \u00d7 60 px.<\/li>\n\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/increase-reduce-signature-kb.jpg\" alt=\"How to increase a 12 KB signature to 30 KB and reduce an 80 KB signature to under 49 KB for RRB NTPC\" class=\"wp-image-180\" srcset=\"https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/increase-reduce-signature-kb.jpg 1200w, https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/increase-reduce-signature-kb-300x169.jpg 300w, https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/increase-reduce-signature-kb-1024x576.jpg 1024w, https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/increase-reduce-signature-kb-768x432.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Two quick fixes to hit the RRB NTPC signature size: add pixels when the file is too small, lower quality when it&#8217;s too big.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rejection-reasons-table\">RRB NTPC signature size rejection reasons and fixes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The notice lists grounds for rejection at any stage, even after you clear the CBT.

Under CEN 06\/2026, the portal opens your camera and captures your face while you apply. Because there&#8217;s no file, there&#8217;s no RRB NTPC photo size in KB or pixels to meet, unlike the RRB NTPC signature size. What matters is light, background and a clear face.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"live-photo-checklist\">Live photo checklist: lighting and background<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Plain white or light wall<\/strong> behind you. No posters, doors or people.<\/li>\n\n\n<li><strong>Dark, plain clothes<\/strong> that cover your shoulders. A white shirt blends into the wall.<\/li>\n\n\n<li><strong>Light in front of you<\/strong>, like a window you&#8217;re facing. Never a bright window or lamp behind you.<\/li>\n\n\n<li><strong>Camera at eye level<\/strong>, face straight on, eyes fully open, neutral expression.<\/li>\n\n\n<li><strong>No cap, mask or spectacles.<\/strong> Keep hair off your face.<\/li>\n\n\n<li><strong>Head should fill at least half the frame.<\/strong> Nothing below your chest should show.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">You can preview and retake the photo until you submit, so zoom in and retake if your face looks dark or blurry. Never photograph an old printed photo or a picture from your gallery. The notice says such applications are rejected outright.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/rrb-ntpc-live-photo-checklist.jpg\" alt=\"RRB NTPC live photo checklist: do&#x27;s and don&#x27;ts for lighting, background and clothes\" class=\"wp-image-181\" srcset=\"https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/rrb-ntpc-live-photo-checklist.jpg 1200w, https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/rrb-ntpc-live-photo-checklist-300x169.jpg 300w, https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/rrb-ntpc-live-photo-checklist-1024x576.jpg 1024w, https:\/\/toolscrush.com\/blog\/wp-content\/uploads\/2026\/10\/rrb-ntpc-live-photo-checklist-768x432.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Set up your room before you open the camera step.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"phone-vs-webcam\">Phone vs webcam: which is better for the live photo?<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Point<\/th><th>Phone front camera<\/th><th>Laptop webcam<\/th><\/tr><\/thead><tbody><tr><td>Image quality<\/td><td>Usually sharper<\/td><td>Often grainy in low light<\/td><\/tr><tr><td>Holding steady<\/td><td>Rest it on a stack of books at eye level<\/td><td>Fixed, but often below eye level<\/td><\/tr><tr><td>Lighting<\/td><td>Easy to turn towards a window<\/td><td>Need to move the laptop to face light<\/td><\/tr><tr><td>Best for<\/td><td>Most candidates<\/td><td>Those filling the whole form on a computer<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If you use a laptop, raise it on books so the webcam is level with your eyes, and switch off any beauty or blur effect in your camera app.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"live-photo-mismatch\">If the live photo doesn&#8217;t match your ID<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the live photo doesn&#8217;t match your photo ID, you may be asked for Annexure VIII signed by a Gazetted Officer.

The form captures a live photo by camera while you apply. You only upload a signature.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"faq-12kb-to-30kb\">My signature is only 12 KB. How do I increase it to 30 KB?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Increase the pixel size, not just the quality. Resize it to about 600 \u00d7 340 px with the Image Resizer, then use the Image Compressor&#8217;s quality slider until the size reads 40\u201345 KB, safely inside the RRB NTPC signature size range.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"faq-reduce-80kb\">How do I reduce an 80 KB signature to under 49 KB?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Open it in the Image Compressor and lower the quality slider in small steps until the size reads 40\u201345 KB. Keep the image at least 140 \u00d7 60 pixels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"faq-ssc-bank-signature\">Can I use the same signature I used for SSC or a bank exam?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Usually not as it is. Those forms ask for 10\u201320 KB, which is below the minimum RRB NTPC signature size of 30 KB. Re-export it at a larger size first.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"faq-signature-dpi\">What does 100 DPI mean for the RRB NTPC signature size?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It means at least 100 dots were captured for every inch of paper. Any clear phone photo or normal scan meets this, as long as the final image is at least 140 \u00d7 60 pixels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"faq-spectacles\">Can I wear spectacles in the live photo?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. Remove spectacles, caps and masks just for the capture, and keep your face fully visible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"faq-wrong-signature\">What if I uploaded the wrong signature?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use the modification window from 9 to 18 November 2026 to replace it with a file that meets the RRB NTPC signature size. A fee of \u20b9250 applies for each occasion you modify the form.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Need sizes for other exams too? Our <a href=\"https:\/\/toolscrush.com\/blog\/resize-photo-and-signature\/\">photo and signature resize guide<\/a> covers SSC, IBPS, SBI, UPSC and NEET.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>This guide is based on RRB NTPC CEN 06\/2026 as published in October 2026.
