Mat coverage is generally appropriate for your standing and movement profile.
Use this estimate with real movement patterns and floor conditions before final purchase.
We can build and embed a custom version of Anti Fatigue Mat Size Calculator for your brand and workflow.
Buying a mat that matches catalog desk width often leaves feet on hard floor. This tool answers: how big should my anti-fatigue mat be for how I actually stand?
Combines 65% of workstation width and 55% of depth with buffers so the mat spans realistic foot placement.
Adds 6–16 cm depth for longer standing exposure to cover forward/back micro-movement over a shift.
Adds 12–34 cm width for low through high side-to-side movement so both feet stay on cushion during reaches.
Default: zone 120 × 70 cm, 6 h standing, medium movement → mat 100 × 49 cm (39″ × 19″), area 0.49 m², coverage ratio 0.58, risk Low.

Preset scenarios using this calculator's formulas. Compare to common retail mat sizes before ordering.
| Scenario | Mat (W × D cm) | Area | Risk |
|---|---|---|---|
| Standard sit-stand desk (120 × 70 cm) | 100 × 49 | 0.49 m² | Low |
| Compact desk (100 × 60 cm) | 77 × 45 | 0.35 m² | Low |
| Wide desk (150 × 80 cm) | 120 × 54 | 0.65 m² | Low |
| Production line (140 × 80 cm, high movement) | 125 × 60 | 0.75 m² | Low |
| Retail label | Approx. cm | Typical use |
|---|---|---|
| 20″ × 30″ | 51 × 76 | Compact — often undersized for medium/high movement |
| 24″ × 36″ | 61 × 91 | Popular desk mat — verify width vs calculator output |
| 39″ × 20″ | 99 × 51 | Compact — often undersized for medium/high movement |
| 47″ × 24″ | 119 × 61 | Wide shallow runner — good when width matches result |
| Level | Added width |
|---|---|
| Low | 12 cm |
| Medium | 22 cm |
| High | 34 cm |
| Hours | Added depth |
|---|---|
| ≤ 5 hours/day | 6 cm depth add-on |
| 5–8 hours/day | 10 cm depth add-on |
| > 8 hours/day | 16 cm depth add-on |
The model scales mat width and depth from your standing footprint, then adds movement and duration buffers. It compares mat area to workstation area to flag likely undercoverage before you order a standard retail size.
Width = max(60, 0.65 × workstation width + movement buffer)Depth = max(45, 0.55 × workstation depth + duration buffer)Area = width × depth (m²)Risk from mat area ÷ workstation area (<0.30 High · <0.45 Moderate · else Low)Pair mat sizing with standing desk height and sit-stand scheduling for full-day comfort strategy.
