Cable Tie Size Chart: Length, Width, Bundle Diameter and Strength
The right cable tie size depends on more than overall length. Buyers should compare at least four model-specific values: tie length, strap width, usable bundle diameter and minimum loop tensile strength. Material, temperature, UV exposure, chemical contact, head clearance and installation method must then be matched to the application.
Yueqing Haitai Plastic Manufacture Co., Ltd. manufactures nylon cable ties and plastic wiring accessories for distributors, OEM buyers and industrial projects. Established in 1999 in Yueqing, Zhejiang, China, Haitai can help buyers compare sizes and request the current drawing, datasheet, material and test-document package for the selected model.
Quick answer: Measure the maximum outside diameter of the completed bundle. Choose a tie whose published usable bundle range includes that diameter, then confirm width, minimum loop tensile strength, material, head clearance and environment. Do not choose by nominal length alone.

How Cable Tie Sizes Are Written
A model described as 4.8 × 300 mm usually indicates:
- 4.8 mm: nominal strap width.
- 300 mm: nominal overall length.
The size name normally does not tell you the strap thickness, head dimensions, usable loop length or minimum loop tensile strength. Those values must come from the exact model drawing and datasheet.
| Specification | Meaning | Purchasing question |
|---|---|---|
| Overall length | Full tie length before installation | Is it long enough to wrap the maximum bundle and enter the head? |
| Ancho de la correa | Nominal width of the tie body | Does it meet strength and routing-space requirements? |
| Grosor de la correa | Thickness of the molded strap | Is it controlled on the current drawing? |
| Bundle range | Smallest and largest recommended closed-loop diameter | Does the actual bundle fall inside the range? |
| Head dimensions | Length, width and height of the locking head | Is there clearance around panels, connectors and moving parts? |
| Minimum loop tensile strength | Pulling performance under a defined test | What value and test method apply to this exact model? |
Metric and Inch Cable Tie Length Chart
Use millimeters for the purchase specification whenever possible. Inch names are often rounded marketing descriptions, so two suppliers’ “8-inch” ties may not have exactly the same length.
| Metric length | Calculated inches | Common search description |
|---|---|---|
| 80 mm | 3.1 in | 3-inch / mini zip tie |
| 100 mm | 3.9 in | 4-inch zip tie |

Width and Tensile-Strength Families
Wider ties are generally associated with higher tensile-strength families, but width alone does not prove the exact performance of an individual model. Head geometry, thickness, material, moisture condition, molding and test method also matter.
Haitai’s old table appears to use merged cells to assign a nominal tensile figure to each width family. The following values are shown only as historical catalog references and must not be published as current certified values until engineering verifies the model scope.
| Historical width family | Old nominal value | Approximate force | Required action |
|---|---|---|---|
| 2.5 mm | 18 lbf / 8 kgf | about 80 N | Verify every current model |
| 3.6 mm | 40 lbf / 18 kgf | about 178 N | Verify every current model |
| 4.5–4.8 mm | 50 lbf / 22 kgf | about 222 N | Verify every current model |
| 7.2–7.6 mm | 120 lbf / 55 kgf | about 534 N | Verify every current model |
| 8.8 mm | 175 lbf / 79.4 kgf | about 779 N | Verify every current model |
Minimum loop tensile strength is a controlled test result. It is not a rated lifting capacity, safe supported mass or universal working load. Application design should account for temperature, duration, vibration, installation stress, chemicals and the consequence of failure.
How to Choose Cable Tie Length
Use the finished bundle diameter
Measure the outside diameter at the largest point after all wires, sleeves and protective layers are in place. If the bundle is irregular, measure its circumference or test it with a representative sample.
Do not equate overall length with circumference
A circular bundle has a circumference of approximately π × diameter, but the tie also needs length for the head, insertion and tightening tail. Head design and usable strap length vary by model. The safest method is to use the manufacturer’s stated bundle range.
Allow for tolerances and installation
Account for the largest bundle tolerance, insulation variation and enough tail for the installation tool. Do not select a tie whose maximum bundle diameter exactly equals an uncertain field measurement.
Check the minimum bundle diameter
A very long or wide tie may not lock correctly around a very small bundle. Compare both ends of the published bundle range.
How to Choose Cable Tie Width and Strength
Two ties with the same length can have different widths, head sizes and tensile performance. For example, a 300 mm tie may be available in an intermediate, standard or heavy-duty width. Select the width after defining:
- Minimum loop tensile requirement and test method.
- Available head and strap clearance.
- Cable insulation sensitivity and allowable contact pressure.
- Manual or tool-controlled installation.
- Static or moving bundle conditions.
- Vibration, temperature and environmental exposure.
- Required material and compliance documents.
Using the widest tie is not always best. A wide strap may reduce available routing space or apply unsuitable pressure to delicate cables. Use the smallest approved model that meets the complete requirement with an appropriate design margin.
Size Is Only One Part of the Specification
After shortlisting a size, match the product type and material:
| Application condition | Product or material to evaluate | Do not assume |
|---|---|---|
| General protected indoor bundling | Standard self-locking PA66 tie | That it is suitable for direct sunlight |
| Direct outdoor sunlight | UV-stabilized black PA66, PA12 or approved alternative | That black color alone proves UV resistance |
| Elevated temperature | Heat-stabilized nylon, PA46 or another approved material | That a room-temperature tensile value proves heat life |
| Chemical exposure | Material tested for the named chemical and conditions | That all plastics resist all chemicals |
| Repeated access | Releasable design | That a standard one-piece tie can be reused safely |
| Large bundle | Extra-long model with verified bundle range | That extra length means extra strength |
| High strength | Heavy-duty model with verified tensile result | That it can be used for lifting or structural restraint |
Provide the actual temperature, UV, humidity, chemical, movement and service requirements instead of ordering by a broad description such as “industrial quality.”
Common Size-Selection Mistakes
- Ordering an “8-inch tie” without confirming whether the actual length is 200 mm or another value.
- Choosing by overall length without checking maximum bundle diameter.
- Assuming every 300 mm tie has the same strength.
- Treating kgf as the safe number of kilograms the tie can support.
- Applying one width-family tensile value to every model without a current datasheet.
- Assuming black means UV-resistant or white means the same as natural nylon.
- Ignoring head dimensions in a compact enclosure.
- Using room-temperature test data to predict long-term hot, cold or outdoor performance.
- Copying catalog conversions without recalculating millimeters and inches.
- Releasing a purchase order without a model, drawing revision and document scope.
Cable Tie RFQ Checklist
Send the following information so Haitai can recommend and quote the correct size:
- Application and destination market.
- Maximum and minimum bundle diameter.
- Preferred length and available head clearance.
- Required width or minimum loop tensile strength.
- Material and color.
- Indoor/outdoor use, UV and weather exposure.
- Installation and service temperature.
- Chemicals, moisture, vibration or movement.
- Quantity by model and expected purchasing frequency.
- Bag count, labels, barcode, carton marks and pallet needs.
- Required datasheets, test reports, declarations or certificates.
- Sample and production schedule.
For model matching, attach the existing drawing, competitor part number, physical sample or clear dimensional photos. Haitai should confirm equivalence by specification, not by part-number appearance alone.
Frequently Asked Questions
What size cable tie do I need?
Measure the maximum finished bundle diameter and select a model whose usable bundle range includes it. Then confirm the length, width, head clearance, minimum loop tensile strength, material and environment.
How are cable tie sizes measured?
Cable ties are commonly named by nominal strap width and overall length, such as 4.8 x 300 mm. Thickness, head dimensions, usable bundle range and tensile strength require the exact model drawing or datasheet.
Is a 12-inch cable tie stronger than an 8-inch cable tie?
Not automatically. Length determines reach, while strength depends on width, thickness, material, locking-head design, manufacturing condition and the test method used for the exact model.
How do I calculate cable tie length from bundle diameter?
A circular bundle’s circumference is approximately pi times its diameter, but extra length is needed for the locking head, insertion and tightening tail. Use the model’s published bundle range instead of circumference alone.
What does minimum loop tensile strength mean?
It is the force reached in a defined loop-pull test under stated conditions. It is not a universal safe working load, lifting capacity or guarantee of performance in every temperature and environment.
What is the difference between cable tie length and bundle diameter?
Length is the tie’s overall end-to-end dimension before installation. Bundle diameter is the size of the object or cable group the closed tie is designed to surround.
Can the same cable tie size be used indoors and outdoors?
The dimensions may fit both, but the material may not. Outdoor use requires evaluation of UV, weather, temperature, moisture and chemicals; black color alone is not proof of outdoor suitability.
What information should I send for a cable tie quotation?
Send the bundle diameter, length, width or tensile requirement, material, color, environment, quantity, packaging, required documents, destination and any existing drawing or sample.
Request the Current Haitai Cable Tie Size List
