Cable Tie Size Chart: How to Choose Width and Length

Published by: VAV Plastik · First published: 2026-09-28 · Last updated: 2026-09-28

Choose cable tie length from the bundle: circumference (diameter × 3.14) plus at least 25% for the tail. Choose width from the job: 2.0–2.5 mm light, 3.6 mm standard panel work, 4.8 mm medium-heavy, 8.0–9.0 mm heavy. The chart below applies this rule to all 31 sizes VAV Plastik stocks.

Wholesale only. Export minimum order: one full pallet (cable tie sizes and tape colours can be mixed). We do not sell single packs, retail quantities or to private individuals.

Step 1 — length from the bundle diameter

  1. Measure the finished bundle diameter (D) in millimetres.
  2. Circumference = D × 3.14.
  3. Add at least 25% so the tail passes the locking head and can be pulled tight.
  4. Pick the first stocked length at or above that figure.

The same rule gives the bundle limits listed for every size on our cable ties page: maximum bundle diameter = tie length ÷ 3.925.

What this chart does not tell you

Tensile strength differs between manufacturers and batches. Catalogues of branded manufacturers publish minimum tensile values by width; those are that manufacturer's declarations, not a property of every nylon tie of the same size. If your specification sets a minimum tensile value, ask us for the manufacturer's data sheet for the batch you would receive before you order.

Frequently asked questions

How do I calculate the cable tie length I need?

Measure the bundle diameter, multiply by 3.14 to get the circumference, then add at least 25% so the tail can pass through the head and be gripped. A 50 mm bundle has a circumference of about 157 mm, so a 200 mm tie is the minimum and 250 mm is more comfortable.

Which width should I choose?

Width sets the duty class. 2.0–2.5 mm for light electronics work, 3.6 mm for panels and indoor installation, 4.8 mm for cable trays and heavier bundles, 8.0–9.0 mm for very thick bundles and pipes.

Can I use cable ties to lift or hang loads?

No. Cable ties are for bundling. Their tensile rating is the force at which the tie breaks, not a safe working load. Use purpose-made fixings for anything that hangs or carries weight.

Is a longer tie always better?

No. A tie much longer than needed wastes material and leaves a long tail that has to be cut. Choose the shortest length that still gives the 25% margin.
