It might seem like a small detail, but picking the wrong shipping label size can cause real headaches — labels that don't fit your packaging, barcodes that get cut off, or rolls that won't load properly in your printer. Getting it right from the start saves time, waste, and frustration.
The most common shipping label sizes
The most widely used shipping label size in the UK is 100mm x 150mm. It's the standard format accepted by the major couriers — Royal Mail, DPD, Evri, DHL, and others — and it fits comfortably on most parcels and poly mailers. If you're just getting started, this is the safe choice.
102mm x 210mm labels are popular with businesses that need more space — for longer addresses, additional barcodes, or return label information. They're commonly used in fulfilment and logistics operations.
Smaller sizes like 50mm x 25mm or 70mm x 36mm are better suited to product labelling, price tickets, or smaller packages where a full shipping label would be overkill.
Other things to consider
Beyond size, it's worth thinking about:
- Core size — most desktop thermal printers use a 25mm or 38mm core. Check before you order.
- Roll quantity — if you're shipping at volume, buying in bulk will save you money and reduce reordering admin.
- Label material — standard paper is fine for most shipping, but polypropylene or polyester offer extra durability if needed.
