How it works

How the Online Garden Planner works

Start with reach

Bed width is decided by your arm, not by the timber

A planting bed only works if you can reach the middle of it without standing on the soil. Comfortable reach for most adults is 24 in to 30 in (60 cm to 75 cm). That makes a bed with access on both sides about 4 ft (120 cm) wide, and a bed against a fence or wall no more than 30 in deep. Beds get built at 5 ft or 6 ft all the time because that is what the boards came in, and the middle row then gets trodden on every season. Draw the beds to scale first and the width settles itself.

  • Bed reachable from both sides: 4 ft (120 cm) wide, no wider.
  • Bed against a wall or fence: 24 in to 30 in (60 cm to 75 cm) deep.
  • Keep bed length under 12 ft (3.6 m) or people will walk across instead of around.
  • Leave 18 in (45 cm) between the back of a bed and a boundary fence so the fence can be maintained.
Access

Plan the paths for a full wheelbarrow, not for walking

Everything heavy in a garden moves on a wheelbarrow: compost in, prunings out, a bag of gravel, a tray of plants. A standard barrow is about 24 in (60 cm) across the handles, so the working path needs 30 in (75 cm) clear and 36 in (90 cm) if it has a corner in it. Narrow paths between beds can drop to 18 in (45 cm), but only where you never need to bring wheels through. Draw the paths as real widths in SpacePlanner rather than leaving them as whatever is left over after the beds are placed.

  • Main working path: 30 in to 36 in (75 cm to 90 cm) so a loaded barrow passes.
  • Path between two beds, foot traffic only: 18 in to 24 in (45 cm to 60 cm).
  • Give a barrow 5 ft (150 cm) of space to turn at the end of a run of beds.
  • Where a wheelchair is used, paths need 36 in (90 cm) and a 60 in (150 cm) turning circle.
What goes where

Sun, water and the compost heap fix half the layout

Before any bed is placed, three things pin the plan down. The sun path decides which end of the plot grows vegetables and which end takes shade planting. The tap decides how far you are willing to carry water, and 50 ft (15 m) of hose is the practical limit before watering stops happening. The compost heap wants to be close enough to use daily but out of the main view. Mark all three on the plan, then place the beds around them. SpacePlanner keeps the house and the garden on the same canvas, so you can see the shadow the building throws across the plot.

  • Put vegetable beds where they get at least 6 hours of direct sun in midsummer.
  • Run beds north to south so plants do not shade each other along the row.
  • A compost bin needs a 3 ft (90 cm) cube to heat up properly, plus space to fork it over.
  • The smallest useful greenhouse is about 6 ft by 8 ft (1.8 m by 2.4 m).
Step by step

From empty canvas to a layout you can trust

1

Set out the growing area and which way it faces

Draw the piece of ground you will actually grow on, not the whole plot, and put the house wall that shades it on the same canvas. Note which way the beds face while you do it, because aspect decides which end of the plot is worth giving to vegetables.

2

Mark the fixed points

Put in the back door, the outside tap, existing trees, the shed and anything else that is not moving. These decide where paths have to run and which corner is worth planting. Everything else in the garden is arranged around them.

3

Lay the paths in before the beds

Draw the working route from the door to the far end of the plot at its real width, 30 in or wider. Gardens designed bed first end up with paths made of leftovers. Path first, and the beds land in sensible sizes on their own.

4

Place the beds and check the reach

Drop the beds in at true size and read the widths off the plan. Anything wider than 4 ft with access on both sides, or 30 in against a fence, gets trimmed now while it costs nothing. Then switch to 3D to see how the beds sit against the house.

Reference

Garden bed, path and planting dimensions

A garden plan fails in the same two places every time: a bed too wide to reach across, and a path too narrow for a loaded wheelbarrow. Both are fixed on paper in a minute and cost a season to fix on the ground. These are the figures worth drawing into the plan before any timber is cut or any turf is lifted.

Working figures for beds, access routes and the space plants actually need.
MeasureImperialMetricWhy it matters
Bed width, access from both sides 4 ft 120 cm Puts the centre within a 24 in reach from either edge.
Bed depth, access from one side only 24 to 30 in 60 to 75 cm For beds against a fence, wall or hedge.
Raised bed height for vegetables 10 to 12 in 25 to 30 cm Enough root room for most annual crops.
Raised bed height for standing work 30 to 36 in 75 to 90 cm Waist height, so no kneeling is needed.
Usable topsoil depth in a planting bed 12 in 30 cm Shrubs and deeper roots want 18 in (45 cm).
Main path, wheelbarrow access 30 to 36 in 75 to 90 cm A standard barrow is about 24 in across the handles.
Path between two beds, on foot 18 to 24 in 45 to 60 cm Enough to stand and work, not to wheel through.
Gap behind a bed to a boundary fence 18 in 45 cm So panels and posts can still be reached and replaced.
Compost bin, minimum working size 3 x 3 x 3 ft 90 x 90 x 90 cm Below this the heap loses heat and rots slowly.
Dwarf fruit tree spacing 8 to 10 ft 2.4 to 3 m Semi-dwarf needs 12 to 15 ft (3.6 to 4.5 m).

FAQ

Online Garden Planner FAQ

Is the online garden planner free?

Yes. The SpacePlanner online garden planner is completely free to use online. You can start drawing instantly without signing up.

Do I need to install anything?

No. It runs entirely in your browser on desktop, tablet or mobile. There is nothing to download or install.

Do I need an account to draw?

No. You can draw a full plan without an account. We only ask you to sign up when you want to save, export or share your work.

Can I plan outdoor spaces too?

Yes. You can plan gardens, patios, backyards, pools and outdoor kitchens alongside indoor rooms on the same canvas.

How do I plan a garden when the plot is not a neat rectangle?

Draw it as it is. Measure each boundary run separately and type the lengths in, and SpacePlanner draws the real shape to scale with a dimension label on every side. Odd corners and tapering plots are normal. Once the true outline is on screen you can see which corners are big enough to be useful and which are only good for planting.

Can I plan the garden and the house together?

Yes. Indoor and outdoor sit on the same canvas, so the house footprint, the back door and the garden beds are all in one plan at one scale. That matters because the route from the kitchen door to the vegetable beds is what decides whether the beds actually get used.

Does the garden planner work in metres as well as feet?

Yes, and you can switch at any time. Bed sizes, path widths and the total plot area all convert together. Useful in a garden, where timber and paving are often sold in metric sizes even when you measured the plot in feet.
