How to Measure PVC Strip Curtains — Measuring Guide
How to Measure PVC Strip Curtains
Getting accurate measurements is the single most important step when ordering PVC strip curtains. Follow this guide to measure your opening correctly every time.
What You Need to Measure
- Opening Width (A) — the clear width of the door or opening, measured inside the frame
- Opening Height (B) — from the underside of the header (or where the rail will sit) to the floor
Step-by-Step Measuring Guide
Step 1 — Measure the Width (A)
Measure the full clear width of the opening from left to right, at the widest point. Do not include the door frame itself — measure the usable opening only. Your rail should match or slightly exceed this width.
Step 2 — Measure the Drop (B)
Measure from where the bottom of the rail will be fixed down to the floor. Add 50mm so strips brush the floor to form a complete seal. This gives your strip length.
Step 3 — Choose Your Overlap
Overlap determines how much strips cover each other — more overlap means a better seal but slightly more resistance when walking through:
- 50% overlap — light pedestrian traffic, minimal sealing needed
- 67% overlap — recommended for most warehouse, workshop and food applications
- 80% overlap — maximum seal for cold rooms, freezers and pest-critical areas
Step 4 — Calculate Strip Count
With 200mm wide strips:
- 50% overlap → each strip covers 100mm → strips needed = Width ÷ 100mm (round up)
- 67% overlap → each strip covers 66mm → strips needed = Width ÷ 66mm (round up)
- 80% overlap → each strip covers 40mm → strips needed = Width ÷ 40mm (round up)
Step 5 — Choose Your Rail Type
| Application | Rail Type |
|---|---|
| Standard doorway, pedestrian | Hook-On Rail (stainless or galvanised) |
| Forklift / loading bay | Swivel Hinge Rail |
| Wide opening, full clearance needed | Twin Track Rail |
| Schools, nurseries, offices | QuickMount Rail (tool-free) |
Quick Reference Strip Count Table
| Opening Width | Strips @ 50% | Strips @ 67% | Strips @ 80% |
|---|---|---|---|
| 1,000mm | 10 | 16 | 25 |
| 1,500mm | 15 | 23 | 38 |
| 2,000mm | 20 | 31 | 50 |
| 2,500mm | 25 | 38 | 63 |
| 3,000mm | 30 | 46 | 75 |
| 4,000mm | 40 | 61 | 100 |
Based on 200mm wide strips. Always round up to the nearest whole strip.
