Not sure what size shed you need? Our shed size planner includes shed sizes explained, garden shed layout ideas, and how to choose the right shed for your garden.

Shed Size Planner: How Much Space Do You Really Need?

Choosing the right shed size is one of the most important decisions you’ll make when investing in a garden building. Whether you’re looking for simple outdoor storage solutions or a fully functional workshop, getting the size right from the start will save you time, money, and hassle later on.

At Ace Sheds, we’ve been helping customers find the perfect fit for over 30 years, so here’s our straightforward guide to help you decide how big your shed should be and how to make the most of your space.

Why Choosing the Right Shed Size Matters

A garden shed is about usability, not just storage.

Too small, and you’ll quickly find yourself running out of room. Too large, and you risk taking up valuable garden space unnecessarily.

The key is finding a balance between:

  • What you need now,

  • What you may need in the future,

  • How you plan to use the space day-to-day.

If you’re still exploring options, take a look at our full range of garden buildings to get a feel for what’s available.

How Big Should My Shed Be?

This is one of the most common questions we get, and the answer always depends entirely on your needs.

Start With What You’ll Use It For

Think about your primary purpose:

Make a quick list of everything you plan to store, which will give you a realistic starting point.

If you need something tailored, our bespoke options allow you to design a shed around your exact requirements.

Don’t Forget About Usable Space

It’s not just about fitting everything in; you need room to move.

Ask yourself:

  • Can I access items easily? 

  • Do I need space to work inside? 

  • Will I be constantly moving things around to reach others? 

A well-sized shed should feel practical, not cramped.

Plan for the Future

What we see time and time again is customers outgrowing their shed.

If you’re unsure, it’s often worth going slightly larger. Choosing a shed with a bit of extra space now can save you from upgrading in the future.

Shed Sizes Explained

At Ace Sheds, our garden sheds come in a range of sizes to provide outdoor storage solutions for you, based on your needs. To make things easier, here’s a simple breakdown of common shed sizes and how they’re typically used.

Small Sheds (4x6 / 6x6)

Ideal for:

  • Basic garden tools 

  • Pots and smaller items 

These are a great choice for compact gardens or where space is limited. Explore our small sheds.

Medium Sheds (6x8 / 8x10)

A popular choice for most gardens:

  • Lawnmowers and tools 

  • Bikes and outdoor equipment 

Browse our range of medium sheds, which offer a good balance between storage and usable space.

Large Sheds (10x12 and above)

Best suited for:

  • Workshops 

  • Hobby spaces 

  • Multi-purpose storage 

If you’re planning to spend time inside your shed, a larger size will make a big difference. Shop our large sheds.

Garden Shed Layout Ideas

Once you’ve chosen your size, layout is what really brings your shed to life.

With the right setup, even a compact shed can feel spacious and organised.

Make Use of Vertical Space

  • Install shelving and wall racks,

  • Hang tools instead of stacking them,

  • Keep the floor clear where possible.

Create Practical Zones

Divide your shed into clear areas:

  • Storage.

  • Workspace.

  • Access.

This makes it easier to stay organised and use the space efficiently.

Keep Everyday Items Within Reach

  • Place frequently used tools near the door.

  • Less-used items can be stored higher or further back.

Simple changes like this can make a big difference in day-to-day use.

Consider Customisation

If you have specific requirements, a custom-built shed gives you complete control over layout, access, and internal space.

Choosing the Right Shed Size for Your Garden

It’s not just about what goes inside; the shed needs to work within your outdoor space too.

Think About Proportion

  • A large shed can dominate a small garden.

  • A smaller shed may suit tighter spaces better.

Allow for Access

Make sure you have enough room to:

  • Open the doors fully.

  • Move around the shed.

  • Carry items in and out easily.

Placement Matters

Position your shed where it’s convenient to use and not tucked away where access becomes difficult.
