4×6 Shipping Label Maker — Free for Thermal Printers

4x6 inches is the standard shipping label size used by UPS, USPS, FedEx, and all major carriers. Our 4x6 label maker generates PDFs sized exactly to 4x6 inches (101.6mm x 152.4mm), optimized for direct-thermal and thermal-transfer label printers. Compatible with Rollo, DYMO 4XL, Zebra ZP450, Brother QL-1110, and any printer that accepts 4x6 label stock. The PDF output uses precise dimensions with no margins, so your label prints edge-to-edge without scaling issues. Set your printer to 'Actual Size' and print — no trimming needed.
