Can I draw a room to scale without a floor plan?

Yes. Choose ‘Enter your room size instead’ on the start screen, type the width and depth, and the room is drawn at true scale. You never need a plan image — although if you have one, uploading it is even quicker than typing.

What scale should I draw a room at?

On screen there is no fixed ratio to choose: ToScale keeps the room and every piece of furniture in the same real-world units and you zoom in and out. If you are drawing on paper, 1:50 (1 cm on paper = 50 cm in the room) fits a single room on an A4 sheet, and grid paper at one square per 10 cm or one square per foot is the easiest to read.

Can I draw an L-shaped room, an alcove or a partition wall?

Yes. Start from the room’s overall width and depth, then use the Walls tool: click each corner in turn and press Esc to finish. Walls snap to each other, and furniture placed afterwards treats them as solid — so a wardrobe will not quietly overlap the alcove.

Does it work in feet and inches?

Yes. Type the room in feet and inches or in centimetres, and switch units at any time — every dimension on the plan updates. Furniture presets carry real sizes in both.

Draw a room to scale

Updated September 4, 2026

Quick answer The fastest way to draw a room to scale is to type its width and depth: ToScale draws it at true size in your browser, free and without an account. Add walls with the Walls tool if the room has an alcove or an L-shape, switch between centimetres and feet, then place furniture at its real dimensions to see what fits. If you already have a floor plan, upload it instead and skip the drawing.

You do not need CAD software to draw a room to scale. Most rooms are a rectangle with a door in it, and a rectangle is two numbers. Type the width and depth into ToScale and the room appears at true scale in your browser — then add walls only where the room is not a plain box, and place furniture at its real size to see what fits. No account, no download, nothing to learn first.

Open the planner and choose ‘No floor plan? Enter your room size instead.’ Type the width and depth, in centimetres or feet, and the room is drawn at that size straight away. If the room has an alcove, a chimney breast or an L-shaped end, pick the Walls tool and click the corners — walls snap to each other, and Esc finishes the run. From then on every piece you add is drawn at its own width and depth against those walls, so the gap you see beside the bed is the gap you will actually have. Switch between metric and feet-inches at any time, export the layout as a PNG, or walk through it in 3D to get a feel for the space. And if you already have a floor plan — a listing screenshot, a photo of a printed plan — upload that instead and skip drawing altogether.

How to draw a room to scale in three steps

Measure the room wall to wall at floor level — its width and depth, and where any alcove, chimney breast or partition starts and ends.
Open ToScale, choose ‘Enter your room size instead’, and type the width and depth in centimetres or feet. The room appears at true scale immediately.
If the room is not a plain rectangle, pick the Walls tool and click its corners. Then add furniture at its real width and depth and drag it into place — the gaps you see are the gaps you get.

Measure the room at floor level, wall to wall, and type the inside dimensions — not the ones from a listing, which are often taken to the widest point. If one wall has a radiator or a built-in cupboard, draw that as a wall too; it takes floor space just like a partition does.

Ways to get a room to scale, and what each one costs you

‘Draw a room to scale’ can mean five quite different jobs, from two numbers to a full afternoon. This is what each approach asks of you and what it gives back, so you can pick the lightest one that answers your question.

Approach	What you have to enter	How long it takes	What it is right for
Type the dimensions (ToScale)	Width and depth, in cm or feet	Under a minute	Any rectangular room — most bedrooms, offices and living rooms — when the question is whether the furniture fits
Type the dimensions, then draw walls (ToScale)	Width and depth, plus the corners of an alcove, partition or L-shape	A few minutes	Rooms that are not a plain box: L-shaped living rooms, bedrooms with a built-in wardrobe, studios with a partition
Upload a plan you already have (ToScale)	One length you know, to set the scale	Under a minute	When a floor plan already exists — a listing, a brochure, a photo of a printed drawing — so there is nothing to draw
Draw from scratch in a room-design app	Every wall, door and window, then the furniture from a catalogue	An hour or more	Designing a whole home, choosing finishes, or producing a 3D render — more than a fit check needs
Graph paper and a tape measure	Every wall, at a fixed ratio such as one square per 10 cm	Half an hour, and again for each new idea	Working offline, or when you want a drawing you can pin to the wall

The first three rows are the same tool starting from different places, and the fourth and fifth are perfectly good at what they are for. What none of them can do is answer a fit question faster than typing two numbers, which is why ToScale starts there and lets you add detail only when the room actually has some.
