Garden Area & Raised-Bed Calculator
Measure rectangles, circles and corner beds, then size raised beds for soil, boards and posts.
- Area in m² and ft²
- Edging length
- Board courses and soil litres
Living Garden planner
Watch your garden grow before you dig a single hole.
Type your bed's length and width and a tiny garden sprouts on screen. Then work out spacing, plant counts, soil, mulch and water with calculators built for real beds, borders and balconies.
3 m × 1.2 m
Each sprout stands for one plant at 30 cm spacing. Large beds show a scaled-down sample.
The planners
Five planners, one tidy garden
Each planner answers one practical question, from "how big is this border?" to "how many litres does it need this week?". Use them in order or jump straight to the one you need.
Plant Spacing & Quantity Calculator
Compare square and triangular layouts and see exactly how many plants fit your bed.
- Crop spacing presets
- Plants per m²
- Spare-plant allowance
Soil & Mulch Calculator
Turn bed size and depth into litres, bags and cubic yards, with a settling allowance built in.
- Metric and imperial volumes
- Bag counts for any size
- Mulch type comparison
Water Requirement Planner
Estimate weekly litres from crop demand, weather, rainfall and your watering method.
- Litres per week and per session
- Rainfall and mulch adjustments
- Watering-can equivalents
Virtual Garden Planner
Drag plants onto a scaled bed and watch spacing and quantities calculate themselves.
- Drag, drop or tap to add
- Automatic plant counts
- Planting summary table
How it works
From tape measure to planting day
Good garden plans are mostly arithmetic done in the right order. The Living Garden keeps that order for you.
Step 1
Measure the space
Start with area. Every later figure, from seedlings to soil bags, multiplies or divides by it.
Step 2
Fill it with plants
Choose spacing for each crop and let the planner count positions, rows and a few spares.
Step 3
Feed and water it
Work out soil, mulch and weekly water so you buy the right amount the first time.
1 litreWater from 1 mm of rain falling on 1 m²
1.2 mA common raised-bed width for reaching the middle from both sides
≈25 mmA widely used weekly water guideline for many vegetable beds
5–8 cmTypical organic mulch depth for weed suppression
All results are planning estimates based on standard formulas and general rules of thumb. Your soil, climate and plant varieties will shift the real numbers, so treat them as a confident starting point rather than a guarantee.
