How it works

How the Backyard Planner works

Zones first

A backyard is a plot divided, not a room furnished

The mistake in most backyard sketches is drawing objects before drawing zones. A yard has to hold several jobs at once: somewhere to sit, somewhere to eat, somewhere for grass, somewhere for planting, and usually somewhere to hide the bins and the mower. Draw the plot boundary to its measured length first, then block out those zones as areas. Only once the areas add up to less than the plot do you start placing a table or a shed. Zones that overlap on paper always overlap in real life.

  • Measure the boundary on all four sides. Very few plots are actually rectangular.
  • Mark the house wall and every door or window that opens onto the yard.
  • Block out sitting, dining, lawn, growing and storage as areas before placing objects.
  • Leave the paths between zones as real widths, not as leftover gaps.
Ground and boundaries

Slope and setbacks decide more than taste does

Two things constrain a backyard before any design choice. The first is drainage: the ground has to fall away from the house, and the usual requirement is 6 in of drop across the first 10 ft. The second is the boundary. Sheds, large trees and pool fencing are frequently subject to a local setback, commonly 3 to 5 ft from a property line for an outbuilding. Draw the boundary and mark the setback as a strip you do not build in. It shrinks the usable plot noticeably, and it is better to see that at the start.

  • Ground should fall at least 6 in over the first 10 ft away from the foundation.
  • Keep outbuildings 3 to 5 ft off the boundary, subject to your local rule.
  • Plant a large shade tree at least 20 ft from the house and from the drains.
  • Run roof downspouts 4 to 6 ft (1.2 to 1.8 m) clear of the wall before the water soaks away.
Circulation and safety

Paths, gates and the clear space around hazards

A backyard path is not a decorative line. A main route needs 48 in so two people can pass and a wheelbarrow can turn. A single access path can drop to 36 in. Gates follow the same logic: 36 in for people, 48 in if a mower has to get through. Hazards then take their own clear zones out of the plan. A fire pit needs 10 ft of clearance from the house, the fence and any overhanging branch, with seating pulled back 36 in from the rim. Play equipment needs a 6 ft fall zone on every side. Draw those circles at true size and the remaining lawn is what you actually have.

  • Main path 48 in, secondary path 36 in, stepping stones 24 in centre to centre.
  • Pedestrian gate 36 in. Widen to 48 in for a mower or wheelbarrow.
  • Fire pit 10 ft from anything combustible, seating 36 in back from the edge.
  • Swings and climbing frames need a 6 ft clear fall zone all round.
Step by step

From empty canvas to a layout you can trust

1

Draw the plot boundary and the house wall

Measure each boundary run and type the length in. SpacePlanner draws it to scale with a live dimension label. Add the rear wall of the house and the doors that open onto the yard, because those doors set where every path has to start.

2

Mark the fixed constraints

Shade the boundary setback strip, the fall away from the house, and anything already there that is staying: a mature tree, a manhole, a washing line post. These are not negotiable, so they go in before anything you get to choose.

3

Block out the zones as areas

Draw sitting, dining, lawn, growing and storage as rectangles at real size. If they do not fit inside the boundary with paths between them, the plan is already too ambitious. Shrink a zone now rather than discovering it later.

4

Place objects and check the clear zones

Drop in the shed, table, fire pit and beds at true size, then check the clearances: 48 in on the main path, 36 in around the shed, 10 ft around the fire pit. Switch to 3D to see how the levels and the planting read from the back door.

Reference

Backyard layout and setback dimensions

Backyard figures come from three different places: drainage and building rules, safety guidance for fire and play equipment, and the practical width a person plus a wheelbarrow needs. They are worth checking together, because the ones that fail a layout are almost always the boundary setback and the space around a fire pit rather than the size of the lawn. Local setback rules vary, so treat those rows as the figure to confirm rather than assume.

MeasureImperialMetricWhy it matters
Main garden path 48 in 122 cm Two people pass, and a wheelbarrow can turn.
Secondary or access path 36 in 90 cm One person at a time. The practical minimum.
Ground fall away from the foundation 6 in over 10 ft 15 cm over 3 m Standard drainage grade. Keeps water off the wall.
Outbuilding or shed to a property line 3 to 5 ft 0.9 to 1.5 m Typical local setback. Confirm your own rule.
Clear working space around a shed 36 in 90 cm Enough to paint, repair and clear leaves.
Large shade tree to the house 20 ft 6 m Keeps roots and canopy off the foundation and gutters.
Small ornamental tree to the house 10 to 15 ft 3 to 4.5 m Scaled to a mature spread under 20 ft.
Fire pit to any structure or fence 10 ft 3 m Also clear of overhanging branches.
Seating back from a fire pit rim 36 in 90 cm Fire pit bowls are commonly 36 to 44 in across.
Fall zone around play equipment 6 ft 1.8 m Clear on every side. More in front of a swing arc.
Downspout discharge from the foundation 4 to 6 ft 1.2 to 1.8 m Extensions carry roof water past the backfill zone.
Overhead clearance above swings and trampolines 24 ft 7.3 m Clear of branches, cables and the shed roof.
Stepping stone spacing, centre to centre 24 in 60 cm Matches a normal stride across a lawn or bed.
Pedestrian gate width 36 in 90 cm Widen to 48 in for a mower or bulk deliveries.

FAQ

Backyard Planner FAQ

Is the backyard planner free?

Yes. The SpacePlanner backyard 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 backyard that slopes?

Draw the flat plan first and mark where the ground drops. SpacePlanner handles levels through stairs, so a sunken lawn or a raised seating area can sit on its own level and connect to the rest of the plan by steps. Keep the fall away from the house at roughly 6 in over the first 10 ft wherever the ground meets the wall.

Can I draw the house and the backyard on the same plan?

Yes, and you should. Indoor and outdoor live on one canvas, so the rear wall of the house is the same wall in both. That matters because the back door position decides where the main path runs, and a yard drawn in isolation almost always puts the path in the wrong place.

How much lawn is left once everything else is placed?

Draw the zones and find out rather than guessing. A shed, a dining area, a fire pit circle and the paths between them regularly account for half a small plot. Because everything is at true size on a scaled plan, the lawn that remains is a real measurement, not an optimistic one.
