Room Layout Planner checkpoint
A 4.6 m × 3.7 m living room is being tested with a furniture group occupying a 2.9 m × 2.05 m bounding rectangle.
Inputs used
| Room length | 4.6 m |
|---|---|
| Room width | 3.7 m |
| Furniture group length | 2.9 m |
| Furniture group width | 2.05 m |
| Desired clearance | 0.7 m |
Calculator result
- Length remaining
- 0.30 m
- Width remaining
- 0.25 m
- Fit assessment
- Fits with the requested clearance
Decision from this checkpoint
If the bounding-box check passes, tape the group and the 700 mm circulation target on the floor before purchasing the largest item.
- Include opened drawers or recliner travel separately.
- Check the delivery route independently from the room fit.

Use the complete product dimensions
Record the furniture width, depth, and height from the exact product specification. Add any different dimensions for reclining, extending, opening, or pulling out. Handles, arms, feet, overhanging tops, and rear clearances can matter in a tight space. A nominal mattress or table size is not always the same as the assembled product footprint.
Map the room constraints around the footprint
Place the furniture footprint on the measured room sketch together with doors, radiators, windows, sockets, floor vents, and fixed storage. Mark the opened position of doors and drawers. Keep the main circulation route visible. This catches layouts that fit mathematically but block access or force people through an impractical gap.
Check the used position
Dining chairs need space to pull back, wardrobes need doors or drawers to open, and recliners can project well beyond their closed depth. Treat these as separate clearance checks rather than adding one generic margin around every object. Where two moving elements overlap, test them together on the plan.
Test the delivery route
Measure entry doors, corridors, stair widths, landings, turns, and lift dimensions where relevant. Compare them with the packaged or transport dimensions supplied by the retailer, not only the assembled dimensions. Removable legs or modular sections can change the route, but confirm what can actually be removed before relying on that assumption.
Mock up before committing
Use painter’s tape, cardboard, or existing furniture to mark the proposed footprint at full scale. Walk the main routes and open nearby doors. A short physical check can reveal scale and access problems that are difficult to judge from a screen. Keep the final dimensions and delivery notes with the order.
