Methodology
How we match
We start from your body, work out the setup it needs, and only then look at products. Every product is scored on how well its published measurements fit you. No brand can pay to change that.
1. Your body sets the targets
Body proportions scale closely with height. From your height we estimate your lower-leg length, thigh length, elbow height and eye height using ratios from ANSUR II, the US Army's 2012 survey of 6,068 people, then add1″ for shoes. That gives your ideal seat height, maximum seat depth, sitting and standing desk heights, and screen height.Try the calculator.
2. Some answers filter
A few answers are deal-breakers. A chair rated below your weight, a desk that can't reach your standing height at all, or a product over your budget is removed, so you only see things you'd actually consider.
3. Everything else is scored
| Product | What we compare |
|---|---|
| Office chairs | Seat height range vs your ideal seat height (±1″), seat depth vs your thigh length (2–4″ clearance behind the knee), weight rating (about 25% headroom, a rule of thumb) and seat width for your weight, then adjustability, lumbar, headrest and material |
| Standing desks | Lowest height vs your sitting desk height (up to 1″ above), highest height vs your standing height (up to 2″ below), lift capacity vs your setup, size |
| Mice | Length and width vs your hand length and grip, weight, shape, buttons |
Inside the tolerance a product scores full marks. Outside it the score falls away gradually, so a near miss can still rank if it's excellent otherwise. The score you see ("92% fit") is the weighted average.
4. Drawn to scale
Products are drawn from their published dimensions on a shared grid, and people at their real proportions, so a bigger chair or a taller desk really is drawn bigger. The drawings are outlines, not photos.
Where the data comes from
Dimensions and capacities come from manufacturers' own spec sheets wherever possible, then Amazon listings. Products we haven't fully verified yet are marked as such. We don't show prices, because Amazon prices change constantly: we link you to the live price instead.
Sources
Body ratios: ANSUR II (US Army, 2012). Design guidance: ANSI/HFES 100-2007 and BIFMA G1-2013 (as quoted in theUniversity of Washington furniture guidelines) and OSHA's computer workstations eTool. Chair weight headroom is a vendor rule of thumb: BIFMA publishes no load-rating method.
What this isn't
Averages are a starting point, not a diagnosis. If you have pain or a medical condition, talk to a doctor, physiotherapist or occupational therapist.
How we make money
When you buy through our Amazon links we may earn a commission, at no extra cost to you. Commissions never affect the fit score, and brands can't pay to be included. Read our disclosure.
