Cable Tie Sizes Chart in mm & Inches
Quick answer: Measure the largest outside diameter of the finished bundle, then choose a cable tie whose usable bundle range includes that measurement. Confirm the tie length, strap width, minimum loop tensile strength, head clearance, material and installation environment before ordering; nominal length alone does not determine fit or strength.
How should a buyer choose a cable tie size?
Start with bundle diameter, not the inch name printed on a bag. A tie also needs enough usable strap for the locking head and installation tail, while width, thickness, material and head geometry determine whether it fits the space and reaches the required strength.
1. Measure
Measure the finished bundle at its widest point, including sleeves and protective layers.
2. Shortlist
Select a published bundle range that covers the real minimum and maximum bundle diameter.
3. Verify
Check current drawing, tensile test basis, material, temperature and packaging for the exact model.
Metric and inch cable tie length chart
Use millimeters on drawings and purchase orders because inch names are usually rounded descriptions. The conversion is inches = millimeters ÷ 25.4; the table shows rounded results and common market names, not a complete list of available SKUs. For example, 1,200 mm equals about 47.2 inches, while exactly 48 inches equals 1,219.2 mm.
| Metric length | Calculated inches | Common description | Buyer note |
|---|---|---|---|
| 80 mm | 3.1 in | 3-inch / mini tie | Fine wire and compact routing |
| 100 mm | 3.9 in | 4-inch tie | Small bundles |
| 120 mm | 4.7 in | 5-inch tie | Check exact millimeter length |
| 150 mm | 5.9 in | 6-inch tie | Small appliance or panel bundles |
| 180 mm | 7.1 in | 7-inch tie | Compact harness routing |
| 200 mm | 7.9 in | 8-inch tie | Common general-purpose length |
| 250 mm | 9.8 in | 10-inch tie | Medium bundle reach |
| 300 mm | 11.8 in | 12-inch tie | Compare multiple width families |
| 350 mm | 13.8 in | 14-inch tie | Confirm maximum bundle diameter |
| 400 mm | 15.7 in | 16-inch tie | Large bundles and longer reach |
| 450 mm | 17.7 in | 18-inch tie | Check width and head clearance |
| 500 mm | 19.7 in | 20-inch tie | Confirm usable bundle range |
| 600 mm | 23.6 in | 24-inch tie | Extra-long applications |
| 710 mm | 28.0 in | 28-inch tie | Check the current model drawing |
| 740 mm | 29.1 in | 29-inch tie | Confirm the selected width family |
| 800 mm | 31.5 in | 32-inch tie | Large industrial bundles |
| 920 mm | 36.2 in | 36-inch tie | Confirm head and installation space |
| 1,000 mm | 39.4 in | 40-inch market name | Check exact millimeter length |
| 1,200 mm | 47.2 in | 48-inch market name | Not exactly 48 inches; specify millimeters |
Haitai 4.8 mm nylon cable tie size chart
The following five models are listed in Haitai’s 4.8 mm standard PA66 series with a catalogue minimum loop tensile strength of 220 N. Maximum bundle diameter is a model specification; it is not calculated by dividing total tie length by pi.
| Model | Width × length | Maximum bundle diameter | Minimum loop tensile strength | Pieces per bag |
|---|---|---|---|---|
| HTS-100ST | 4.8 × 100 mm | 22 mm | 220 N | 100 |
| HTS-200ST | 4.8 × 200 mm | 50 mm | 220 N | 100 |
| HTS-300ST | 4.8 × 300 mm | 80 mm | 220 N | 100 |
| HTS-500ST | 4.8 × 500 mm | 150 mm | 220 N | 100 |
| HTS-920ST | 4.8 × 920 mm | 265 mm | 220 N | 50 |

Does a wider cable tie always have more tensile strength?
A wider tie usually belongs to a higher strength family, but width alone does not prove the result of a specific SKU. Minimum loop tensile strength must be tied to the exact model, conditioning and test method; it is not a lifting capacity or universal safe working load.
| Nominal width family | Catalogue minimum loop tensile strength | Common purchasing use | Product specification |
|---|---|---|---|
| 2.5 mm | 80 N | Small signal wires and light bundling | 2.5 mm model table |
| 3.6 mm | 180 N | Appliance and general panel wiring | 3.6 mm model table |
| 4.8 mm | 220 N | General industrial and larger harnesses | 4.8 mm model table |
| 7.2–7.6 mm | Specified by the selected model | Heavy-duty cable management | View the 7.6 mm series |
| 8.8 mm | Specified by the selected model | Extra-heavy-duty bundles | View the 8.8 mm series |
The 80 N, 180 N and 220 N values come from the N columns of the linked Haitai product tables. Rounded commercial pound-force labels are not substituted for catalogue N values; the current model specification and agreed test conditions govern each order.
Why source cable tie sizes from Haitai?
Yueqing Haitai Plastics Manufacture Co., Ltd. manufactures nylon cable ties for distributors, OEM programs and industrial buyers. The following company-level facts describe supply experience; product performance and certificate scope are still verified by SKU.

Frequently asked cable tie size questions
What size cable tie do I need?
Measure the largest finished bundle diameter and choose a current model whose usable bundle range includes it. Then verify width, tensile strength, material, head clearance and environment.
How are cable tie sizes measured?
A description such as 4.8 × 300 mm normally means nominal strap width × overall length. Thickness, head dimensions and usable bundle diameter require the current model drawing.
Is a 12-inch cable tie stronger than an 8-inch cable tie?
Not automatically. Length determines reach, while strength also depends on width, thickness, material, head design, molding condition and test method.
How do I convert cable tie sizes from millimeters to inches?
Divide millimeters by 25.4. Use the millimeter dimension and tolerance on the purchase specification because the inch name may be rounded.
What should I send for a factory quotation?
Send bundle diameter, preferred length and width, tensile requirement, material, color, environment, quantity, packaging, destination and required documents. A sample, drawing or competitor reference can speed up model matching.
Send the bundle diameter and order requirements
Haitai can match the requested size to a current model, sample, packaging format and applicable technical documents.
