Shipping Label Sizes and Formats Explained: 4x6 Thermal vs A4 Sheets
Dimensional Comparison of E-Commerce Labels
Understanding label dimensions helps you select the correct label stock and prevent wasted packaging materials:
- 4x6 Inches (100x150 mm / 288x432 pt): The universal standard across Flipkart, Meesho, Amazon, BlueDart, Delhivery, and Ekart. Ideal for envelopes, poly mailers, and corrugated boxes.
- 4x4 Inches (100x100 mm): Used for compact parcels and domestic express couriers with simplified routing codes.
- A4 Sheet (210x297 mm): Standard office printer size combining customer invoices with small shipping quadrants. Inefficient for high-volume dispatch.
Financial Analysis: Thermal Rolls vs A4 Sheets
Printing 1,000 orders on A4 sheets requires 1,000 sheets of 75 GSM paper (₹350), 1 laser toner cartridge portion (₹400), 10 rolls of clear packaging tape (₹300), and hours of manual cutting. Printing the same 1,000 orders on 4x6 direct thermal rolls requires 1 roll of self-adhesive labels (₹450) and zero toner, saving over ₹600 per 1,000 orders and cutting packing labor by 70%.
