4×6 Thermal Labels are self-adhesive labels that measure exactly four inches wide and six inches tall. They’re the go-to size for shipping and logistics because they fit perfectly on most packages and are approved by major carriers like USPS, UPS, FedEx, and DHL. Printed with thermal technology, these labels don’t require ink or toner, making them a cost-efficient choice for businesses.

Why 4×6 Is the Standard Size

The 4×6 Thermal Labels format ensures easy barcode scanning, clear text, and enough space for shipping details. This universal size also helps businesses avoid reprints and delivery delays.

Direct Thermal vs. Thermal Transfer

  • Direct Thermal: Prints by applying heat directly to the label surface. Best for short-term use like shipping.

  • Thermal Transfer: Uses a ribbon to transfer ink, creating more durable 4×6 Thermal Labels ideal for long-term storage or harsh environments.

Advantages of Using 4×6 Thermal Labels

  • No ink or toner costs

  • High-speed printing for bulk orders

  • Crisp, professional appearance

  • Compatible with a variety of printers
