What Size Shed Do I Need?
A practical way to think about shed size before you call, based on what you will store and how you need to move around the space.
The right shed size is the footprint that holds your belongings, leaves room to move and still works with the route into the garden. Start with how you will use the building, not only the empty space available.

A simple four-step sizing method
- Write down the biggest itemsInclude bikes, lawnmowers, wheelbarrows, bins, garden furniture and anything that needs to stand upright.
- Add the storage you wantThink about shelves, hooks, a workbench, tool racks and a clear place for seasonal items.
- Leave working spaceAllow the door to open fully and leave enough room to wheel, lift or carry items into position.
- Test the footprint outsideUse string, chalk or canes to mark the width and depth on the ground before you commit.
Useful starting points for common needs
These are rough planning examples, not fixed recommendations. Door positions, wall thickness, roof overhangs and the shape of the garden can change what works.
6 x 4 ft
Useful for basic tools, a few boxes and compact garden equipment where access is easy.
8 x 6 ft
A flexible starting point for tools, shelving, a mower and some room to move around.
10 x 8 ft
Better suited to several bikes, larger equipment, a bench or a hobby-style layout.
Do not forget door clearance and access
- Leave room for the door to open without hitting a wall, fence or stored item.
- Keep a clear route to the items you use most often.
- Measure the narrowest gate and passageway on the delivery route.
- Remember the roof may overhang the walls and need clearance from boundaries.
- Consider whether the base, drainage and maintenance space fit the larger footprint.
Storage needs change over time
A shed that fits today’s boxes may feel small once you add bikes, garden furniture or a workbench. If the space allows, a little extra width can be more useful than filling every corner with tall storage. For bikes, use the bike shed calculator for a rough starting point.
