The most common reason a photo poster underwhelms is not the printer - it is the file. Get the source right and the print looks the way you hoped.
Start with the right file
Share the original photo from your phone or camera - not a screenshot, not a message copy. iOS: use Share → Save to Files. Android: use the original file from Google Photos, not the shared preview.
Aim for at least 300 dpi at print size. For A3 that is roughly 3500 × 4900 px. Our editor shows a live print-quality badge, so if the file is too small you will see it before you buy.
Pick a size that suits the wall
A4 sits nicely on a shelf or a small alcove. A3 is our most popular photo size - big enough to feel like art, small enough for any UK frame.
A2 is the right pick above a sofa or bed. A1 is for a feature wall with plenty of clearance around it.
Three mistakes to avoid
1. Uploading a heavily filtered photo - most Instagram filters look washed out in print. Trust the raw file.
2. Cropping in the editor without planning - decide the crop in your Photos app first so you don't lose the top of anyone's head.
3. Choosing A1 with a phone photo taken in low light - noise that is invisible on screen is very visible on paper at 594 mm wide.
