These 6" x 4" Royal Mail thermal labels (152.4 x 101.6mm) are the UK's most widely used shipping label size and the standard format for Royal Mail and all major couriers. Ideal for printing clear, professional shipping labels at home or in the workplace.

Made from premium direct thermal paper with a superior coating, these labels deliver guaranteed scanability with sharp, fade-resistant barcodes that stay legible throughout transit. Manufactured to exacting standards, they protect your print head from damage and ensure consistent performance—unlike low-quality imports that risk equipment failure and poor adhesion.

The precisely applied permanent acrylic adhesive bonds securely without glue bleed or printer contamination, eliminating common quality issues from cheaper alternatives.

BPA-free and compatible with all standard thermal label printers, these labels are the dependable choice for online sellers and small businesses who value reliable, professional results.

Each roll contains 500 labels on a 1" (25.4mm) core (roll diameter: 126.55mm)—the best combination of value and quality for worry-free shipping.
