About this tool
Plan room dimensions, arrange furniture pieces, check spacing, save layouts, and export printable floor plans.
The Furniture Layout Planner adds up the real footprint of the furniture you own, compares it with your room's floor area, and checks the result against standard residential clearance rules — 91 cm (36 in) for a main walkway, 61 cm (24 in) beside a bed, 46 cm (18 in) between a sofa and a coffee table and 91 cm to pull a dining chair out. It is for anyone measuring up before buying a sofa or moving into a new room, and it applies the widely used guideline that furniture should cover no more than 60% of the floor. Piece sizes are standard manufactured dimensions, including ISPA mattress sizes.
Open Furniture Layout Planner on AltFTool — it loads instantly in your browser.
Enter Room width (cm) and Room length (cm), plus Doorways into the room and an optional TV screen diagonal in inches.
Press Add piece and choose from the catalogue, where each option is labelled with its standard size such as "Queen bed (60x80 in) — 152 x 203 cm", then set a quantity.
Read Floor covered by furniture against the 60% guideline with each clearance warning, then press Copy plan or print the to-scale floor plan.
Uses standard manufactured footprints, so the numbers match what shops actually sell.
Every warning cites the specific minimum it failed, in centimetres and inches.
Draws a deterministic wall-hugging arrangement you can print and mark up.
Leave 91 cm (36 in) for a main walkway through a room and at least 61 cm (24 in) for a secondary path, such as one side of a bed. Between a sofa and a coffee table the target is smaller — 46 cm (18 in) — because you reach across it rather than walk through.
Keep the furniture footprint under about 60% of the floor area, leaving 40% open. In a 15.6 sq m (168 sq ft) bedroom that means roughly 9.4 sq m of furniture; a queen bed, two bedside tables, a wardrobe and a chest come to about 4.7 sq m, so there is plenty left.
Allow 91 cm (36 in) from the table edge to the wall so a chair can be pushed back, and 112 cm (44 in) where someone also has to walk behind a seated diner. A 180 cm table therefore wants a room at least about 3.6 m across.
Between 1.2 and 1.6 times the screen diagonal — the THX 40-degree and SMPTE 30-degree viewing-angle recommendations. For a 55-inch screen that is roughly 168 cm to 224 cm of seating distance.
