A photo mug lives or dies on the photo, and most disappointing ones were disappointing before they were printed. The print area on an 11 oz mug is roughly 20 cm wide and 8.5 cm tall, it wraps around a curve, and it is looked at from arm's length while someone drinks tea. That combination rewards some photographs and punishes others. Here is how to tell which is which before you order.
The shape problem: mugs are landscape
Phones take portrait photos. Mugs are landscape. A tall photo of one person standing up either gets cropped to a band across the middle or shrunk with empty space either side. Neither looks intended.
Fixes, in order of preference: choose a landscape photo; or crop a portrait photo tightly to the face and shoulders so it becomes square, which sits comfortably on one side of the mug; or use two photos, one on each side, which is what the personalised photo mug is set up for, with a front image and a back image uploaded separately.
Faces need to be big
A photo of six people at a table looks lovely on a phone screen and turns into six small ovals on a mug. The rule of thumb: if a face is smaller than a fingernail on your phone screen, it will be smaller than a fingernail on the mug. One or two people, close up, is the photo that works. A grandparent with one grandchild; a dog looking at the camera; a couple on a step. Group photos belong on a mouse pad, which is flat and bigger.
Light, contrast and the white glaze
The mug is white, and the design is fused into the glaze by sublimation, which prints colour but not white. Pale parts of a photo are simply the mug showing through. Two consequences:
- Over-exposed photos (bright sky, washed-out faces) lose their pale areas entirely. A slightly darker, evenly lit photo prints better than a bright one.
- Dark, moody photos print dark. That is fine for a portrait against a black background; it is less fine for a photo taken in a pub at night, where the noise in the shadows becomes visible grain.
Daylight, no direct flash, subject facing the light: that is the photo that prints closest to how it looks on screen.
Resolution: what "clear enough" means
Any photo taken on a phone made in the last eight years is more than sharp enough, as long as it is the original. The ones that print soft are copies: a photo saved from WhatsApp, a screenshot of a photo, a picture downloaded from Facebook. Each of those has been compressed and shrunk. Ask for the original from whoever took it, or use the version in your own camera roll. A useful check: zoom in on the face on your phone; if it goes blocky quickly, it will print soft.
For the technical minimum, a photo at least 1,500 pixels on its long edge prints cleanly on a mug. Most phone photos are 3,000 to 4,000.
Backgrounds and busy photos
On a curved 8.5 cm surface, detail turns into texture. A photo with a plain or softly blurred background prints as a photo; a photo with a busy background (a crowd, foliage, a cluttered room) prints as a pattern with a face in it. If the only photo you have is busy, crop in tighter.
Old photos and scans
Old prints scan well if the scan is done at 600 dpi or higher and the print is flat. A photo of a photo taken with a phone under a lamp carries a glare stripe and a colour cast; on a mug that stripe becomes permanent. If the photo matters, take the phone picture in daylight by a window, straight on, with no flash, then crop the edges.
Text with a photo
Short. A name and a date, or one line such as "Grandad's mug" or "Est. 2024", in a colour taken from the photo. Long wording competes with the picture and has to shrink; on a mug that means it becomes unreadable first. Our mug wording guide has fifty ideas that fit, and the font guide covers which style suits a photo.
A quick checklist before you upload
- Landscape or square, not tall portrait.
- One or two faces, large.
- Original file, not a screenshot or a forwarded copy.
- Even daylight, no flash glare.
- Plain or blurred background.
- Wording short, one line.
Everything is printed to order in Cheshire, usually dispatched within one to three working days, with free UK delivery. Because the mug is fused with the photo you send, it cannot be returned for a different photo, so the checklist is worth the minute. If you are unsure whether a photo will work, email it to support@larencraft.com before ordering and we will tell you honestly. More photo options are compared in gift ideas.
Frequently asked questions
What resolution does a photo need for a mug?
At least 1,500 pixels on the long edge. Any original phone photo from the last eight years is fine; screenshots and photos forwarded through messaging apps are not, because they have been compressed.
Can I put two photos on one mug?
Yes. The photo mug takes a front image and a back image, uploaded separately, with optional text.
Why do pale parts of my photo look faded on a mug?
Sublimation prints colour but not white, so pale areas show the white glaze through. A slightly darker, evenly lit photo prints closer to how it looks on screen.
