Shed Buyer’s Guide: What size garden shed do I need?

Did you know that over 9.6 million UK homes, around 52% of the population, own a garden shed? Yet many homeowners still ask themselves, what size garden shed do I need? Picking the right size matters. Too small and you will quickly run out of space. Too big and your garden might feel cramped. This guide takes you through shed sizes, features, and other factors so you can choose the best fit for your garden.

What Size Shed Should I Buy?

The right size depends on how you plan to use your shed and the amount of garden space you have. A smaller shed is fine for tools, a mower, or garden accessories. If you want space for a workshop, hobby area, or multiple storage needs, a medium or large shed will be more suitable.

It is also wise to think ahead. Many shed owners find they soon fill the shed with garden furniture, bikes, or DIY equipment. It is common to hear people say they wish they had bought a bigger size. Planning for the future now can save you the trouble of replacing or upgrading too soon.

What are the most popular size sheds?

Popular shed sizes include 6x4, 7x5, and 8x6 feet. These are practical for average gardens, offering enough room for tools, a lawnmower, or a couple of bikes without dominating the space.

For households with greater storage needs, or for those wanting a shed that doubles as a hobby room, a 12x8 shed is also a common choice. It provides generous space while still fitting comfortably in medium to large gardens. These standard sizes are a good place to start if you are unsure.

Small sheds: Do I need one?

Small sheds, usually between 4x4 and 8x8 feet, are ideal for compact gardens. They are tidy, practical, and perfect for items like tools, hoses, or seasonal decorations. They also tend to be easier to install and look after.

However, think about your long-term needs. A small shed might be fine at first but could soon feel crowded if you add bulkier items such as a lawnmower or outdoor furniture. For light storage or where garden space is limited, a small shed is a sensible option.

Medium sheds: The versatile option

Medium sheds, from 8x8 to 12x12 feet, offer more flexibility. They can hold larger items like bikes, BBQs, and garden furniture, while leaving space for shelves or benches.

Many medium sheds come with double doors, making it easier to move equipment in and out. They strike a balance between space and size, offering plenty of room without overwhelming the garden. If you want a shed that adapts to different uses, a medium shed is often the best choice.

Large sheds: When bigger is better

Large sheds, usually over 12x12 feet, are designed for those who need plenty of room. They can comfortably store bikes, garden furniture, BBQs, and even machinery like ride-on mowers. With space to spare, they are also suited to use as workshops, gyms, or hobby rooms.

Many large sheds have dual entrances, giving easier access and allowing you to separate different uses. If your garden has the space, a larger shed offers flexibility and reduces the risk of running out of room.

Other Shed Considerations That Affect Size

Door and ceiling height

When choosing a shed, do not just focus on the floor space. Check the height too. Low doors or ceilings can make a shed uncomfortable, especially if you are tall. Measurements matter for both storage and comfort.

Plan how you will use it

Think carefully about the shed’s purpose. A small shed may be fine for simple storage, but if you plan to spend time inside for hobbies or gardening, you will need more space, better access, and possibly features like windows for ventilation.

Where Should I Position My Shed?

The shed size you choose should also work with your garden layout. Place it on a solid base and leave space around it for air circulation and maintenance. Consider sunlight, weather, and how it will fit within the overall look of your garden.

Picking A Roof Style

Roof style can affect how much usable space you get. An apex roof gives extra headroom in the centre, which is useful if you need more height. A pent roof slopes one way and works well next to fences or walls, making it a good choice for narrow gardens. Hip and barn-style roofs are strong designs often used on larger sheds, particularly in areas with harsher weather.

Window And Door Options

Windows and doors also influence which size will suit you best. Double doors are often necessary for medium or large sheds if you want to store larger equipment. A single door is usually fine for smaller sheds. Windows can add light and ventilation, while windowless designs are more private and secure. When deciding on size, check whether your items will pass comfortably through the door.

Shed Planning Permission

When choosing shed size, it is important to keep planning rules in mind. Most sheds in the UK fall under permitted development, so no formal permission is needed. To qualify, a shed must be less than 2.5 metres high at the eaves, with a maximum height of 4 metres for a pitched roof or 3 metres for a flat roof. It must also not take up more than half of the land around the original house.

If a shed is built within two metres of a boundary, the maximum height is 2.5 metres regardless of roof type. Sheds must also be behind the house, not in the front garden, and they cannot be used as permanent living spaces.

For small and medium sheds, planning is rarely an issue. Larger sheds, however, may need approval. Rules can vary locally, particularly in conservation areas, near protected trees, or beside listed buildings. It is always worth checking with your council before you start.

What are the potential consequences of not complying with planning rules in the UK?

Ignoring planning rules can create real problems. In the worst case, local authorities may order you to remove the shed at your own expense. You could face fines or enforcement notices to make changes. Insurance may not cover sheds put up without permission, and unresolved issues can make selling your property more difficult. Non-compliance can even lower property value. Taking time to check the rules first avoids unnecessary stress later.

Final Thoughts

So, what size garden shed do I need? The answer depends on your storage needs, garden space, and how you intend to use it. Small sheds work well for basic storage, medium sheds are versatile, and large sheds give maximum flexibility. Remember to factor in height, placement, planning rules, and budget too. With the right choice, your shed will be a practical and lasting addition to your home.
