Choosing a 20×12 Shed: Dimensions, Storage and Layout
A 20×12 shed has nominal dimensions of 20ft x 12ft, approximately 6.10m x 3.66m. This large footprint suits a workshop with dedicated tool storage, a garden equipment store, or a combined hobby and storage building. Plan the interior around the items you use most often, leaving room to open cupboards, handle materials and manoeuvre machinery. Check the finished internal dimensions before deciding on opposing benches or shelves. Door position and window placement should support your working layout, as well as how you approach the building from the garden. Free assembly is included on all our wooden sheds, with optional wall and roof insulation and colour paint treatment available.
How much space does a 20ft x 12ft shed provide?
The nominal footprint is 240 square feet, approximately 22.30 square metres. Usable internal space will be smaller and depends on the building’s construction and any lining. Check the exact external measurements, internal dimensions, door opening and roof overhang before ordering.
Is a 12×20 shed the same as a 20×12 shed?
Reversing the dimensions describes the same rectangular area, but it may indicate a different frontage, depth or door arrangement. Check the selected model’s drawing so the entrance faces the right direction and you can use the available space effectively.
Can a 20×12 shed combine storage and workshop space?
A 20×12 shed can combine these uses when the equipment and working clearances fit the usable internal space. Mark out the bench, shelves and bulky items before ordering. Keep a clear route through the building and allow room to handle materials, open cupboards and move bicycles or machinery. Check the floor specification for any heavy equipment.
Compare All Available 20×12 Sheds and Workshops
Compare the following 16 designs with a 20ft x 12ft option. Select or request the 20×12 configuration on the product page, and confirm the exact dimensions, specifications, and available options before ordering.
Sapphire Swanwick and Cadnam sheds
Choose from standard-height Swanwick and tall-height Cadnam ranges in three roof styles:
Platinum sheds and workshops
Platinum Winchester summer rooms
The page also includes these configurable Winchester buildings. They are marketed as summer rooms, so compare their glazed doors, windows and layout with your intended storage or hobby use:
Compare the cladding, framing, roof covering, doors and layout of each model. Confirm the door opening and window arrangement offered for your selected 20×12 configuration, especially if you need to move bulky equipment inside.
Should I choose an apex, pent or reverse apex roof?
An apex roof has two slopes meeting at a ridge; a pent roof has a single slope. A reverse apex changes the orientation of the pitched roof and entrance layout. Compare the chosen model’s overall height, entrance position and roof drainage direction. For a 20×12 footprint, a long-side entrance may suit a different bench and storage arrangement from an end entrance. Check the product drawing rather than choosing by roof appearance alone.
Check the detailed specification for timber treatment, cladding, framing, floor, roof covering, glazing and fittings. Photographs alone cannot show every construction detail or confirm the layout of your chosen size.
Wall and Roof Insulation and Colour Paint Treatment
Can I order an insulated 20×12 shed or workshop?
Optional wall and roof insulation is available on the Sapphire sheds, and the Platinum shed/workshop and Winchester ranges listed above. Confirm the insulation and internal lining specification for your selected 20×12 shed, including any reduction in usable space. Insulation may help if you plan to spend time inside, but heating, ventilation and moisture management need separate consideration.
Explore our insulated sheds and ask the team to quote for the options suited to your intended use.
Can I choose a painted 20×12 shed?
Optional colour paint treatment is available. Browse our painted sheds for finish information and inspiration. Confirm the available shades, finish and maintenance requirements for your chosen model.
A colour that complements your fencing or planting can help the shed sit comfortably in the garden. If the shade is important, ask about samples: photographs, lighting and screens can change its appearance.
Assembly Service, Base Preparation and Garden Access Information
Free assembly is included on all our wooden sheds. You must have a suitable prepared base and adequate garden access ready for installation. Confirm delivery coverage and any location or access restrictions before ordering.
What base does a 20×12 shed need?
Your shed needs a firm, flat and level base built to the selected model’s requirements. Obtain the exact base dimensions before starting work; the nominal 20ft x 12ft description is not a construction plan. An uneven foundation can affect alignment and door operation.
See our base preparation and additional garden building services if you need help preparing the site. Base preparation is separate from the included shed assembly.
What garden access should I check?
Measure gateways, narrow passages and tight corners between the delivery point and the base. Tell us about steps, slopes, low overhead clearance or access through a building so the team can assess the route for the shed panels before installation day.
Expert Advice from Robin Antill and Help Before You Order
Robin Antill, founder of 1st Choice Leisure Buildings, began working with sheds and garden buildings in 1979. His background in manufacturing and selling timber buildings informs the practical advice we give customers about construction, layout and installation.
Robin recommends checking more than size and price. Compare the floor, framing, roof and door fittings, and plan how you will reach your stored equipment. For a 20×12 shed, think carefully about reaching equipment along the full twenty-foot length. Ask about the available door positions if an entrance along the longer side would simplify access. Check bench depth and working clearances against the internal width, and confirm floor suitability and the door opening for heavy or bulky equipment.
Visit our Surrey garden building show site at Sutton Green, near Guildford and Woking to inspect representative buildings. Contact us first if you want to see a particular model or size, as every configuration may not be on display.
