Garage Floor Plan
A garage floor plan starts with the cars, then fits storage and a workbench around the space needed to open their doors and walk past. This page gives typical single, double and triple garage sizes, door widths, the space to leave around each car and how a garage connects to the house. The example is a 6.0 × 6.5 m (20 × 22 ft) double garage with a workbench and shelving that you can open and change.

Typical garage sizes
| Metric (typical) | Imperial (typical) | Fits | |
|---|---|---|---|
| Single | 3.0 × 6.0 m to 3.6 × 6.6 m | 10 × 20 ft to 12 × 22 ft | One car with storage along one side |
| Double | 5.5 × 6.0 m to 7.3 × 7.3 m | 18 × 20 ft to 24 × 24 ft | Two cars, or one car and a workshop |
| Triple | 9.0 × 6.6 m and up | 30 × 22 ft and up | Three cars, or two and a workshop |
What sets the size of a garage
Start from your vehicles. A mid-size car is roughly 1.85 m wide and 4.9 m long (6 × 16 ft) without mirrors (a 2025 Toyota Camry is 1.84 × 4.92 m, 72.4 × 193.5 in, according to Kelley Blue Book); a compact is nearer 4.6 m (15 ft); SUVs and pickups are larger, so measure your own. Add the space to open doors on each side, the space at the front to walk round, and the depth of any bench or shelving.
Garage sizes vary a lot between countries and builders, and the smallest garages in the table are tight for larger cars. If the garage also holds bikes, bins or a workshop, size it for those too.
Garage layouts
Storage along the back wall
A workbench and shelves at the back keep the sides free for car doors. The example plan uses this layout, with shelving on each side of the bench.
Storage along one side
Shelves on the side wall work in a deeper or wider garage; leave space for the car door on that side.
Workshop bay
In a double garage, one bay can become a workshop with benches on two walls.
Laundry or utility corner
A washer and a counter by the door into the house keep laundry out of the living space.
Garage doors, the house door and windows
Garage doors are commonly about 2.4–2.7 m (8–9 ft) wide for one car in North America and about 2.3–2.5 m elsewhere; a double door is often around 4.9 m (16 ft), or two single doors with a pier between them. Put the cars in line with the door so you drive straight in.
A door into the house usually goes at the back or side, away from where car doors open, with a step or landing if the floor levels differ. A window or two on the side wall gives daylight to a workbench. In the editor, add an opening to a wall and type its width to show the garage door.
Space around cars and benches
Allow roughly 60–90 cm (2–3 ft) beside each car to open its doors and walk past, and about 1 m (3 ft) in front of a workbench to work at it. In the example, the dashed car outlines leave about 70 cm (2′ 4″) to each side wall, 75 cm (2′ 6″) between the cars and 65 cm (2′ 2″) to the bench.
The outlines are only for scale; they are not part of the plan when you open it. Mark parking spaces with dimension lines and text labels instead.
Garage items in the library
The library has no cars, but its Storage section has garage pieces: a storage shelf, a tool chest, a pegboard and a step ladder. A counter makes the workbench.
Counter
180 × 60 cm (5′ 11″ × 2′). A workbench: resize it to your bench length.
Storage shelf
100 × 40 cm (3′ 3″ × 1′ 4″). Shelving units; the example has one on each side of the bench.
Tool chest
60 × 30 cm (2′ × 1′). Beside the bench, clear of the car doors.
Pegboard
120 × 3 cm (3′ 11″ × 1″). On the wall above the bench for hand tools.
Washer
60 × 60 cm (2′ × 2′). For a laundry corner.
Fridge
70 × 70 cm (2′ 4″ × 2′ 4″). A second fridge or freezer.
Storage and the link to the house
Most garages end up as the home’s main store, so plan the storage zones: tools by the bench, garden things near the outside door, bikes where they can leave without moving a car. Wall shelving 40–60 cm (16–24 in) deep keeps the floor clear.
An attached garage often opens into a utility room, mudroom or hallway rather than straight into a living space, which gives somewhere to leave boots and coats. Rules on fire separation between an attached garage and the house apply in many countries; check them before planning the connecting door.
Common garage planning mistakes
Sizing for today’s car
The next car may be wider or longer. Leave a margin, especially in length.
Shelving where doors open
Storage along the sides of a narrow garage stops car doors opening. Put it at the back, or make the garage wider.
No walkway to the house door
If you have to squeeze between the car and the wall to get inside, the route is too tight.
Forgetting the garage door mechanism
Overhead and sectional doors need headroom and ceiling space when open; note them on the plan.
Plan your garage in the editor
Open the example
Or draw the garage against your house plan so they share a wall.
Add the garage door
Drag an opening from the library onto the front wall and type its width; add a door into the house with D.
Mark the cars
Use the dimension tool (Shift+D) and text labels to show where each car parks.
Fit the storage
Place counters and shelving, then check the side clearances with the measure tool.

Frequently asked questions
What is a typical double garage size?
Many double garages are between about 5.5 × 6.0 m (18 × 20 ft) and 7.3 × 7.3 m (24 × 24 ft). Bigger cars and storage along the sides need the larger end.
How wide is a single garage?
Commonly about 3.0–3.6 m (10–12 ft), which leaves room to open the doors of an average car. Narrower garages fit the car but make getting out awkward.
How wide is a double garage door?
Often around 4.9 m (16 ft) in North America; elsewhere 4.5–5.5 m is common. Two single doors are an alternative.
Can I add a car to the plan?
There is no car in the furniture library. Mark the parking space with a dimension line and a text label instead.
Can I draw a garage attached to the house?
Yes. Draw it against the house on the same floor. Once walls enclose it, the garage is detected as its own room and appears in the area schedule.
