When it comes to safe packaging and shipping, the right
carton sealing tape is vital. Not all tapes are created equal though, tape width, thickness, and length all have a significant impact on getting the right fit for your packaging application. In this guide, we’ll take you through measuring a carton sealing tape so you can choose the correct one for your company.
Carton Sealing Tape Measurements
Carton sealing tapes are measured by three factors:
- Width: The width of the tape is measured from edge to edge and how much surface area it covers.
- Thickness (Mil Rating): The thickness of the tape is measured in mils (1 mil = 0.001 inches) and how durable it is.
- Length (Yardage): The length of the tape is how much tape is on a roll, measured in yards or feet.
How to Measure the Width of a Carton Sealing Tape
The sealing tape width is critical in determining how well the tape sticks to your box. The standard widths are:- 2 Inches (48mm) – The most common size and often used for standard shipping boxes.
- 3 Inches (72mm) – Ideal for heavier boxes or those requiring extra reinforcement.
- 4 Inches (96mm) and Up – Used for industrial applications and oversized cartons.
Tip: When sealing large or heavy-duty packages, a wider tape provides a larger surface adhesion and a reduced possibility of tape failure.
Understanding Carton Sealing Tape Thickness (Mil Rating)
Tape thickness is gauged in mils, and the higher the mil rating, the stronger and more durable the tape. Here’s how you select the proper thickness:- 1.6 Mil – 1.9 Mil: Lightweight tape for light packages.
- 2.0 Mil – 2.5 Mil: Standard duty, ideal for most shipping and storage uses.
- 3.0 Mil – 3.5 Mil: Heavy-duty tape for sealing heavyweight boxes.
- 4.0 Mil and Up: Industrial-strength tape for extreme conditions and extra reinforcement.
Tip: If your boxes will be in storage for a long time or shipped under extreme temperatures, use thicker acrylic or hot melt tape for increased adhesion.
How to Measure the Length of a Carton Sealing Tape
Carton sealing tape comes in various lengths, with the most common sizes including:- 55 Yards (165 ft.) – Industry standard for smaller applications.
- 110 Yards (330 ft.) – Day-to-day shipping needs standard.
- 1000+ Yards (Machine-Length Rolls) – For use in automatic carton sealing machines.
Tip: If you're using a great deal of tape, seek out longer rolls to reduce tape changes and boost productivity.
Choosing the Right Carton Sealing Tape for Your Needs

| | 1.6-1.9 Mil, 2” Width, 55-110 Yards |
|
| | 2.0-2.5 Mil, 2-3” Width, 110+ Yards |
|
| | 3.0-3.5 Mil, 3” Width, 110+ Yards |
|
| | 4.0+ Mil, 3-4” Width, 1000+ Yards |

Final Tips for Measuring & Using Carton Sealing Tape
- Measure the width correctly – Wider tapes provide stronger adhesion.
- Select the right thickness – Thicker tape works best for heavier or high-value shipments.
- Use longer rolls for high-volume packaging – Reduces roll changes and improves efficiency.
- Pair with the right tape dispenser – Ensures smooth application and reduces waste.
