Equipment dimensions
The footprints the planner places, in feet. These are the numbers that decide whether a room works, and they are the ones most buying guides leave out. Every figure here is what the tool actually uses — the table is generated from the same catalogue, so the two cannot disagree.
| Equipment | Footprint | Height | Clearance to allow |
|---|---|---|---|
| Power rack | 4 × 4 ft | 7.5 ft | Leave ~2 ft of walk-in space at the front. |
| Squat stand | 4 × 2.5 ft | 7 ft | No safeties — keep it near a wall, not centered. |
| Flat bench | 4 × 1.2 ft | 1.5 ft | — |
| Adjustable bench | 4.2 × 1.7 ft | 1.8 ft | — |
| Barbell + plates | 7.2 × 1.6 ft | 1.6 ft | You lift around it — keep a ~7×7 ft open zone. |
| Dumbbell rack | 4 × 1.8 ft | 2.5 ft | — |
| Kettlebell set | 2.5 × 1 ft | 1.2 ft | — |
| Cable / functional trainer | 4 × 3.5 ft | 7 ft | Allow ~3 ft in front for full cable travel. |
| Wall-mounted folding rack | 4 × 2 ft | 7.5 ft | Folds to ~5 in deep against the wall when stowed. |
| Treadmill | 3 × 6 ft | 4.5 ft | Keep ~3 ft clear behind for belt run-off / safe dismount. |
| Exercise bike | 3.5 × 2 ft | 4 ft | — |
| Recumbent bike | 5 × 2.4 ft | 3.8 ft | — |
| Rowing machine | 8 × 2 ft | 1.7 ft | Long — stores upright, but needs the full length in use. |
| Plyo box | 2 × 2 ft | 2 ft | — |
| Storage shelf | 3 × 1.5 ft | 6 ft | — |
| Gym mat (4×6) | 4 × 6 ft | 0.06 ft | — |
The one that catches people out is the barbell. A 7.2 ft bar in a 10 ft room leaves 14 inches total — seven per side — and that is your entire margin for loading plates. Footprint is rarely the binding constraint; clearance is. We measured what this does to a real garage in the garage space study.
Room presets
Start from a real room rather than a guess. Each preset is a common real-world size:
| Room | Dimensions | Floor area |
|---|---|---|
| 8 × 8 room | 8 × 8 ft | 64 sq ft |
| 10 × 10 room | 10 × 10 ft | 100 sq ft |
| 12 × 12 room | 12 × 12 ft | 144 sq ft |
| Spare bedroom (11 × 12) | 11 × 12 ft | 132 sq ft |
| Single-car garage (12 × 20) | 12 × 20 ft | 240 sq ft |
| Two-car garage (20 × 20) | 20 × 20 ft | 400 sq ft |
| Basement corner (14 × 16) | 14 × 16 ft | 224 sq ft |
| Shed (10 × 12) | 10 × 12 ft | 120 sq ft |
Any custom size between 5 and 40 ft per side also works.
How it works
- Set your room. Choose a preset (single-car garage, spare bedroom, 10×10, and more) or type custom dimensions.
- Add equipment. Click any item to drop it in. Each piece uses its real footprint in feet.
- Arrange it. Click and drag on the floor to move, rotate in 90° steps, and delete. Overlaps and anything that spills outside the room turn red.
- Save or share. Copy the link (your layout lives in the URL) or download a PNG.
Plan smarter

FAQ
- Is the home gym planner free?
- Yes — it's completely free and needs no signup. Plan your layout, share the link, or download a PNG at no cost.
- How accurate are the equipment sizes?
- Every item uses a real-world footprint in feet (a power rack is 4×4 ft, a treadmill about 3×6 ft, a barbell 7.2 ft long, and so on), so the fit and clearance warnings reflect what will actually happen in your room.
- Can I save or share my plan?
- Your layout is stored in the page URL as you build, so bookmarking or copying the Share link preserves it. You can also download a PNG snapshot of the 3D view.
- Is this a floor plan designer or a 3D configurator?
- Both, in the sense that matters: you set the room's real dimensions and the tool draws a to-scale floor plan you can rotate in 3D. It is not CAD — there are no walls to draft or doors to place. It answers one question, which is whether the equipment you want actually fits the room you have, with room left to use it.
- Does it work on mobile?
- Yes. Drag to orbit, pinch to zoom, and tap an item to select and move it. A larger screen is easier for detailed layouts.
