A productive vegetable garden depends as much on layout as on what you plant: orientation to the sun, enough space between rows, and paths you can actually reach into. This guide covers the core planning decisions for a raised-bed vegetable garden, plus worked examples for two of the most common raised bed sizes, 4×8 and 3×6.
Start with sun and orientation
Most vegetables need full sun — see plants for full sun for the general principle. For layout specifically:
- Orient long, narrow beds north-south where possible, so taller plants don’t shade shorter ones for most of the day as the sun moves.
- Place your tallest crops, such as staked tomatoes or trellised beans or cucumbers, on the side of the bed that casts the least shade on the rest — typically the north side in the Northern Hemisphere, the south side in the Southern Hemisphere.
- Leave the sunniest side of the bed open — don’t let a fence, wall or hedge shade it for a large part of the day.
Bed width and reach
- Keep beds no wider than about 4 feet (120cm) if accessible from both sides, or 2 feet (60cm) if accessible from one side only, so you can reach the middle without stepping on the soil.
- Paths between beds should be at least 18-24 inches (45-60cm) wide for comfortable access, wider still if you use a wheelbarrow or garden cart.
- Compacted soil from stepping on beds is one of the most common self-inflicted layout mistakes — width and path planning prevents it more reliably than good intentions.
Spacing crops within the bed
Spacing depends on the crop, but the layout principle is the same: plant in blocks or offset grids rather than single rows where bed width allows, since this uses the growing area more efficiently than traditional row spacing designed for field cultivation. For specific spacing, check each crop’s own guide — see the vegetable growing hub for guides to tomatoes, peppers, carrots, lettuce and more.
Grouping plants by height and need
- Tall or vertical crops such as tomatoes, pole beans or trellised cucumbers — along the shaded-side edge, so they don’t block light to shorter crops.
- Medium crops such as peppers or bush beans — through the middle.
- Low or root crops such as carrots, lettuce or radishes — along the sunny front edge or wherever light is least obstructed.
- Grouping by water need also helps: thirstier crops together make watering more efficient and reduce both under- and over-watering.
Worked example: a 4×8 raised bed layout
A 4×8 foot (about 1.2 x 2.4m) bed is wide enough to need access from both long sides. A simple layout: one end, about 2 feet, for a trellis of pole beans or cucumbers along the shaded edge; the middle 4 feet for pepper or bush bean blocks; and the remaining 2-foot end for a lettuce, carrot and radish block that’s quick to succession-sow as it’s harvested.
Worked example: a 3×6 raised bed layout
A 3×6 foot (about 0.9 x 1.8m) bed is narrow enough to reach across from one side, so access matters less for orientation but sun still does. A workable split: a 2×3 foot section for two to three staked tomato plants along the back, a 2×3 foot section for peppers or bush beans, and the remaining strip for a fast-growing leafy or root crop.
Growing under cover
If you’re extending the layout into a greenhouse or polytunnel, see the best vegetables for greenhouses — the same height and shade-grouping principles apply, adjusted for the more sheltered environment.
Common layout mistakes
- Tall crops shading short ones — the single most common layout error; fix with north-south orientation and height grouping.
- Beds too wide to reach — leads to soil compaction and awkward harvesting.
- No path planning — narrow or missing paths make routine access such as watering, harvesting and weeding harder than it needs to be.
- Ignoring soil first — layout only pays off in soil that actually supports root growth; see best soil for raised beds before finalizing a layout.
Quick questions
Which way should a raised bed face? Orient long beds north-south where possible, and keep the sunniest side open so nothing shades the bed for a large part of the day.
How wide should a raised bed be? About 4 feet if reachable from both sides, or 2 feet if reachable from one side only, so you never need to step on the soil.
Where should tomatoes go in a raised bed? Along the side that will cast the least shade on the rest of the bed as they grow tall — typically the north side in the Northern Hemisphere, south side in the Southern Hemisphere.
