Home gym space calculator
Updated 2026-10-23
Quick answer: Add about 18 inches to each equipment dimension for clearance and 12 inches to its height for the ceiling (our planning rules of thumb). Enter your room and equipment sizes below, and the calculator shows whether each box fits the floor and clears the ceiling.
How it works
- Room footprint = length × width (sq ft).
- Clearance footprint = (equipment length + 18 in) × (equipment width + 18 in), our rule of thumb; use the maker's clearance if the manual gives one.
- Ceiling needed = equipment height + 12 in.
- Overhead reach = your height + your measured arm reach. If you have not measured, plan roughly your height plus about 2 feet (our planning estimate, not a measured figure).
Planning numbers: clearance footprint
| Example item | Footprint | With clearance |
|---|---|---|
| Rack, 48 × 48 in | 16 sq ft | 66 × 66 in (30.3 sq ft) |
| Flat bench, 48 × 24 in | 8 sq ft | 66 × 42 in (19.3 sq ft) |
| Dumbbell rack, 36 × 18 in | 4.5 sq ft | 54 × 36 in (13.5 sq ft) |
Planning numbers: ceiling height
| Equipment | Listed height | Ceiling to plan for |
|---|---|---|
| REP PR-1050 short power rack | 72 in | 84 in (7 ft) |
| REP Arcadia functional trainer | 80.8 in | 92.8 in |
| REP Arcadia Max | 87.6 in | 99.6 in |
| Force USA G3 all-in-one | 87 in | 99 in |

People also ask
Is a 10x10 room big enough for a home gym?
A 10 × 10 room is 100 sq ft. One 48 × 48 in rack with 18 inches added to each dimension (our planning rule of thumb) takes about 30 sq ft, so a rack, bench and dumbbells usually fit. Run your own sizes in the calculator.
Is 200 sq ft enough for a home gym?
200 sq ft is twice a 10 × 10 room, enough for several clearance zones like the ones above. Check ceiling height and floor load too; they can limit you before floor area does.
