The 4x6 inch label is the universal shipping standard across Indian e-commerce marketplaces (Meesho, Flipkart, Amazon, Myntra) and major third-party logistics partners (Delhivery, Blue Dart, Xpressbees, Shadowfax). Whether you are purchasing thermal paper rolls, configuring printer drivers, or designing label templates, here are the exact measurements in every standard unit.
Quick measurement reference table
| Measurement Unit | Width | Height | Usage Notes |
|---|---|---|---|
| Inches | 4.0 in | 6.0 in | Standard US & international specification |
| Millimetres (Exact) | 101.6 mm | 152.4 mm | Mathematical conversion (25.4 mm/inch) |
| Millimetres (Sold in India) | 100.0 mm | 150.0 mm | Standard roll size sold on Amazon, IndiaMART |
| Centimetres | 10.0 cm | 15.0 cm | Approximate packaging measure |
| Pixels at 203 DPI | 812 px | 1218 px | Standard desktop thermal printers (TSC, TVS, Xprinter) |
| Pixels at 300 DPI | 1200 px | 1800 px | High-density industrial thermal printers |

Is 100 x 150 mm the same as 4 x 6 inch?
For all practical printing purposes, yes. A true 4x6 inch sticker measures 101.6 × 152.4 mm. Thermal label rolls manufactured and sold in India are rounded down to 100 × 150 mm (1.6 mm narrower and 2.4 mm shorter). Every thermal printer treats them identically. When printing CropMyLabels vector output, selecting 100 × 150 mm with scale set to 'Fit' aligns the label with zero distortion.
Why 203 DPI is the e-commerce industry standard
Most commercial desktop thermal printers operate at 203 DPI (dots per inch). At 203 DPI, 1 mm equals approximately 8 dots. This resolution is optimized for standard Code 128, GS1-128, and QR codes used by Indian couriers. Higher 300 DPI printers produce sharper miniature fonts, but for logistics shipping labels, 203 DPI is fully compliant and highly cost-effective.
