Getting a passport photo taken at a studio used to feel like the only sensible option. You paid, you sat on a wobbly stool, you got four tiny prints, and half the time you hated how you looked.

You can do the whole thing at home now, with just a phone and a plain wall. The photo itself is not hard to take. Where most people get tripped up is the boring technical bit afterwards: exact size in pixels, head position, background colour, and the file size limit on the application form. Get one of those wrong and your passport, visa or ID application gets rejected before a human even looks at it.

This guide walks you through what the requirements actually are, how to take a clean photo without studio kit, and how to resize and crop it to the correct passport photo size using free online tools, no signup, no Photoshop skills needed.

Passport photo size: what you need to know first

There is no single worldwide passport photo size. Annoying, I know. But most countries fall into one of two camps.

The 35 x 45 mm size: Used by the UK, most of Europe, Indian passports (listed there as 3.5 x 4.5 cm) and plenty of other countries. In inches that's roughly 1.38 x 1.77 inches.

The 2 x 2 inch size: Used by the USA for passports and visas, and by India for visa and OCI applications. That's 51 x 51 mm: a perfect square.

If you are applying online, forget millimetres for a second and think pixels. That is what the form actually checks.

  • UK digital passport photo: at least 600 pixels wide and 750 pixels tall, file between 50KB and 10MB
  • US visa (DS-160) photo: square, 600 x 600 to 1200 x 1200 pixels, JPEG, 240KB or smaller
  • Online visa and admission forms: often ask for 200 x 230 pixels, or a file under 50KB, 100KB or 300KB: it varies wildly

Always check the exact requirement on your application page before you crop. A photo that is perfect for a UK passport will be rejected by a US visa form simply because it is the wrong shape.

Your face needs to take up most of the frame too. Your head (chin to top of hair) usually has to fill between half and three-quarters of the photo's height: the US asks for 50-69%, while the UK's 29-34 mm on a 45 mm photo works out at about 64-76%. Standing too far away is one of the most common reasons home photos fail.

Background, lighting and format requirements

Official photos are picky for a reason (they are used for face matching), but the rules are not complicated once you read them properly.

Background: Plain and light, with no patterns, shadows or other people. The US wants white or off-white; the UK wants cream or light grey. A painted wall works far better than a bedsheet, which wrinkles and shows lines. Stand about half a metre away from the wall so you do not cast a shadow behind your head.

Lighting: Even light on your face, no harsh shadows, no red-eye. The easiest setup at home is facing a window in the daytime, with the window in front of you, not behind you. Avoid overhead yellow bulbs if you can: they make skin look blotchy.

Clothing and appearance: Wear something that contrasts with the background, so not a white shirt against a white wall. No hats or head coverings unless for religious or medical reasons, no sunglasses, and (for most countries) take glasses off if you can. Keep a neutral expression, mouth closed, eyes open and looking straight at the camera.

Format: Almost every online form wants JPEG (.jpg). Some accept PNG, but JPEG is safer. Colour photo, recent (the UK wants one taken in the last month, the US in the last six months), and not filtered or retouched. Those beauty filters on your phone? Turn them off.

How to take a passport photo at home, step by step

1. Set up your spot Pick the plainest light-coloured wall in the house. Tidy hair off your face, and move any pictures or clutter out of the frame.

2. Get the light right Do it in the morning or afternoon near a window. Face the light. If one side of your face looks darker, turn slightly or move closer to the window until it evens out.

3. Position the phone Prop the phone at eye level, about 1 to 1.5 metres away. Use a stack of books or a tripod if you have one. The rear camera is sharper than the selfie camera, so if someone can take it for you, even better. Leave space around your head and shoulders: you will crop tighter later.

4. Take more photos than you think you need Take 10-15 shots. Check each one zoomed in: eyes sharp, no blur, no shadow across the face. This is where most people rush. Don't.

5. Pick the best one and check the basics Head straight, not tilted. Both ears visible if possible. Background clean. If the background is a bit grey or uneven, that is fixable later with a background remover, but a clean wall will save you the trouble.

How to resize and crop your passport photo to the exact size

This is the part that rejects most DIY photos, not the photo quality, but the dimensions. The good news is you do not need to install anything.

Step 1: Crop to the right shape first Open the free Image Cropper on xplosole.com and upload your photo. Crop it so your head and shoulders fill the frame, keeping your face centred. For a 35 x 45mm photo, crop taller than wide. For a 2 x 2 inch photo, crop square. Leave a little headroom above your hair: most guidelines want a small gap, not your hair touching the edge.

Step 2: Resize to the exact pixel size Now open the free Image Resizer on xplosole.com and enter the pixel dimensions your form asks for: for example 600 x 750 pixels for a UK digital photo, or 600 x 600 for a US one. Keep the aspect ratio locked while resizing so your face does not stretch.

Step 3: Check the file size If the form says "under 200KB" and your file is 2MB, it will not upload, however perfect the photo looks. If needed, run it through an Image Compressor after resizing, and aim for just under the limit rather than crushing it to 20KB and losing quality.

Step 4: Save as JPEG and re-check Download the final file as .jpg, open it once to confirm it looks sharp, and compare it side by side with the sample photo on the application website. That two-minute check saves a rejection letter.

All of this runs in your browser on xplosole.com, so your photo is not sitting on some random server, and there is no account to create just to download your own picture.

Common mistakes that get passport photos rejected

The same five errors come up again and again:

  • Photo taken too far away, so the face is tiny in the frame
  • Shadow on the face or on the wall behind
  • Wrong dimensions: submitting a rectangle where a square 2 x 2 inch photo was required
  • File too large for the upload limit, so the form silently fails
  • Sunglasses, heavy filters, or a big smile with teeth showing

Most of these are 30-second fixes if you catch them before you submit.

Frequently asked questions

What is the standard passport photo size in pixels? For UK and European applications it is usually 600 x 750 pixels (35 x 45mm print size). For US applications it is a square of 600 x 600 to 1200 x 1200 pixels (2 x 2 inches in print). Always confirm on your specific form, as visa and admission portals sometimes use smaller sizes like 200 x 230 pixels.

Can I take a passport photo with my phone? Yes. Modern phone cameras are more than sharp enough. Use the rear camera if you can, face a window for even light, and keep the phone at eye level. The quality is rarely the problem: size and background are what cause rejections.

What background colour is required for a passport photo? It depends on the country: white or off-white for the US, cream or light grey for the UK. Whatever the colour, it must be plain, without shadows, patterns or other objects, and strongly coloured walls will fail automated checks.

How do I resize a photo to passport size without Photoshop? Upload it to a free Image Resizer, like the one on xplosole.com, enter the exact pixel width and height your application asks for, crop it with an Image Cropper first if the shape is wrong, and save it as JPEG. No software to install and no signup needed.

Can I wear glasses in a passport photo? It depends on the country. The US does not allow glasses in passport and visa photos unless you have a medical reason and a signed statement. Countries that allow them usually require no glare, no tint, and frames that don't cover your eyes, so taking them off is the safest choice.

Taking your own passport size photo at home is genuinely not difficult once you know the dimensions you are aiming for. Take it in good light against a plain wall, crop it properly, resize it to the exact pixels requested, and check the file size before you upload. Do that, and your home photo will pass the same checks as one from an expensive studio booth.
