The four shapes, and what each is for
Most photo magnets come down to four formats. A 2 by 2 inch square is the portrait size: one face, cropped close, nothing else competing. The 2.5 inch square adds enough room for two people or a little background. A 2 by 3 inch rectangle keeps the proportions a phone camera already shoots, so groups and landscapes survive intact, and it is the shape save-the-dates use. A 2.25 inch circle crops away every corner, which forces attention onto a single subject and breaks up a wall of squares.
Test the door before you spend anything
This is the step people skip and regret. Not every refrigerator is magnetic. Integrated units have wooden or laminate fronts with nothing steel behind them, and several stainless finishes use alloys that hold nothing at all. Stick any magnet you own to the intended spot and let go. If it slides or drops, the door is out, and the side panel, the dishwasher, a range hood, or a steel memo board on the wall is the answer instead. Confirm this before ordering, particularly when buying for somebody else's kitchen.
How many pieces one door can hold
There is a practical ceiling and most first orders sail past it. A standard door carries roughly six to twelve photo pieces before the effect tips from display into clutter, and fewer if the same surface is already holding a calendar and school letters. Six is a good opening number. It fills a visible area, leaves somewhere for next year's to go, and costs little enough to repeat. The display layouts article covers the arrangements that hold up once pieces start accumulating.
What the crop costs you
Sizes are not interchangeable, because forcing a picture into the wrong ratio removes part of it. A phone photograph is a rectangle. Push it into a square and roughly a quarter of the frame disappears, which is fine for a single face in the middle and fatal for a group standing in a line. Check what leaves the frame before choosing the shape, not after. Where the photograph has people at the edges, take the rectangle. The product options guide explains the safe area that decides how close to the edge a face can sit.
Close crops beat wide scenes on a kitchen door
A refrigerator gets looked at in motion, by someone holding a coffee on the way past, so a tight face wins over a panorama every time. A 2.25 inch circle pulls the eye to a single subject, while a 2.5 inch square leaves room for a second person or a little background. Wide holiday shots that look spectacular on a phone shrink to a smear at this size. Save those for a rectangle, or for a frame.
Mixing shapes so it does not read as filler
A grid of identical squares looks like packaging. A few circles among the squares, or one larger piece anchoring a group, makes the arrangement look chosen rather than accumulated. Group by year, by child, or by trip, and leave a clear gap between groups so each one registers separately. The display layouts article sets out five arrangements worth copying.
Letting the pictures hold the paperwork
Most doors already carry plain magnets pinning school letters and menus. Rather than build a separate photo display beside that clutter, let the photo pieces do the pinning. A child's portrait holds their sports schedule; a holiday shot sits over the takeout menu. The working corner stops feeling clinical, and the pictures stay in daily use instead of turning into decoration nobody looks at after the first fortnight.
Looking after the door finish
Smooth magnets are generally gentle on an appliance, but lift them straight off rather than sliding them across a stainless front, where trapped grit is what leaves fine lines. If you are buying for somebody house-proud, a slightly thicker piece is easier to grip and less likely to get dragged. It is a small courtesy, and it keeps a present feeling considered instead of like a risk to a new kitchen.
