Robot Safety — Mesh Opening vs Safety Distance
Mesh Opening vs Safety Distance calculation per the machinery-safety standards (ISO 13855/13857, ISO 10218, ISO/TS 15066).
A 40 mm mesh demands 200 mm of standoff; go to 50 mm openings and a whole ARM fits — the requirement jumps to 850 mm. This cliff is why fence suppliers love 40×40 mesh: it is the largest opening that still allows a tight cell. Verify odd-shaped slots against the standard's full table.
Formula
Note: Safety calculations here are layout-planning aids ONLY. The legally required values must come from the cited standards' full tables and a documented risk assessment by a qualified person.

About Robot Safety — Mesh Opening vs Safety Distance
Robot Safety — Mesh Opening vs Safety Distance computes the governing relationship ISO 13857 Table 4 — slot/square openings, regular shape (arm/finger reach-through) live as you type. A 40 mm mesh demands 200 mm of standoff; go to 50 mm openings and a whole ARM fits — the requirement jumps to 850 mm. This cliff is why fence suppliers love 40×40 mesh: it is the largest opening that still allows a tight cell. Verify odd-shaped slots against the standard's full table. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.

Why use Robot Safety — Mesh Opening vs Safety Distance?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula ISO 13857 Table 4 — slot/square openings, regular shape (arm/finger reach-through) with authoritative sources cited on the page (ISO 13855 — Positioning of safeguards w.r.t. approach speeds; ISO 13857 — Safety distances (upper/lower limbs); ISO/TS 15066 — Collaborative robots: power & force limiting)
- ✓A 40 mm mesh demands 200 mm of standoff; go to 50 mm openings and a whole ARM fits — the requirement jumps to 850 mm.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the robot safety — mesh opening vs safety distance use?+
It evaluates ISO 13857 Table 4 — slot/square openings, regular shape (arm/finger reach-through), exactly as published. Sources: ISO 13855 — Positioning of safeguards w.r.t. approach speeds; ISO 13857 — Safety distances (upper/lower limbs); ISO/TS 15066 — Collaborative robots: power & force limiting. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
A 40 mm mesh demands 200 mm of standoff; go to 50 mm openings and a whole ARM fits — the requirement jumps to 850 mm. Safety calculations here are layout-planning aids ONLY. The legally required values must come from the cited standards' full tables and a documented risk assessment by a qualified person.
When is this calculator the right tool for the job?+
Mesh Opening vs Safety Distance calculation per the machinery-safety standards (ISO 13855/13857, ISO 10218, ISO/TS 15066). A free industrial robot kinematics & cell design tool. This cliff is why fence suppliers love 40×40 mesh: it is the largest opening that still allows a tight cell. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
