What size shed do I need?

Choose the smallest shed that lets you store and retrieve your equipment comfortably. A nominal size such as 6 × 4 ft is a shopping label, not a promise about the clear floor space or door opening.

Take four sets of measurements

1. The contents. Record width, depth and height in the position each item will occupy. Include handles, wheels, baskets and attachments.
2. The usable interior. Ask for internal dimensions, including the lowest roof height. Shelves, wall framing and roof braces can interrupt the space.
3. The opening. Check clear door width and height, threshold and whether both leaves of a double door open fully.
4. The site. Allow for the roof overhang, door swing, assembly access and the maintenance clearances specified by the maker.

A floor-area example

Suppose a mower occupies 0.6 × 1.0 m and a second item occupies 0.5 × 0.6 m. Their rectangular footprints total 0.9 m². That does not mean a shed with 0.9 m² of floor is suitable: you still need a workable arrangement and access to the door. These are example measurements, not typical product dimensions.

The storage size planner keeps that distinction visible. It estimates occupied floor area from your measurements; it cannot promise that every shape packs neatly into a particular shed.

Try the everyday journey

Mark out the proposed clear interior. Put the most frequently used item nearest the proposed door and walk through the arrangement. Imagine a wet day when you want the mower back inside quickly. Leave access to any anchor, lock or shelving you plan to use.

Long tools need a separate check. A rake that stands beneath the ridge may not stand at the lower side wall. A bike may fit lengthways yet be awkward to turn through a narrow door.

Check the site before buying

Planning rules depend on the nation, property and location. The planning guide explains the main England checks and directs readers elsewhere in the UK to their local authority. Include the finished base when discussing the proposed height; don't choose a tall shed on the assumption that every garden building is exempt.
