How to measure your site before getting a garden shed
Putting in a garden shed might seem simple, and in many ways it is, but you will need to plan ahead to get it right. Measuring the space for a proposed garden shed before you start the installation process minimises costly mistakes in the long run with accurate measurements to refer to as you go.

When it comes to how to measure a garden shed, be sure to include the space for the overall structure such as drainage, pipes, and the roof overhang.

The type of garden shed you choose will also affect how much space it occupies—whether it’s a flat or skillion roof model, or if it has a traditional gable style or heritage design. 

And you don’t need to stop at limited flat-pack designs, with the right strategy you can customise your garden shed to add extra wall height, doors, windows, or skylights to have a finished structure that is exactly suited to your needs. 

Of course, no matter the design you still need to have easy access and move around freely inside, so measuring the space for features like workbenches and storage shelves ensures that your garden shed will have enough storage while still giving you room to work and find what you need easily.

Unlike garages that need a solid foundation for stability, a garden shed is a simple, versatile structure that can be used as a workshop, a home gym, or a simple storage space. It can be built on skids, wooden platforms, or a pad of concrete. 

When should I measure precisely for my Garden Shed?

  • Garden sheds are usually squeezed into tight spaces, leaving little margin for error. Measuring your garden shed will give you a clear picture of how big you can go without obstructing any existing structures around it
  • Customised garden sheds can further maximise underutilised areas of your property. Even if you have a larger area of space to spare, most gardens can’t easily accommodate big storage structures. By customising your garden shed, you can fit into any sized or shaped “dead area” on your property to make that space functional.
  • Accurate measurements of your garden shed also ensure that it won’t infringe on any neighbouring properties. Without measuring a garden shed you run the risk of installing the wrong dimensions and crossing boundary lines. Fixing these mistakes can blow out your budget and will take time to rebuild.
  • Getting the internal dimensions right is important too. Make a list of the items that you plan to put into your shed, both now and in the foreseeable future so you can allocate the right amount of space and have good access to everything you need. This will help you determine how much space you need and if anything else needs to be taken into consideration (i.e. larger doors for bigger items or vertical storage options like shelves).

What should I consider to accurately measure for a garden shed?

There’s a lot that goes into measuring a garden shed and missing even one element can affect the entire structure. Here’s what you need to take into consideration to get accurate measurements:

  • Shed dimensions - This includes measuring the height, length, and width of your garden shed.

  • Roof overhang - Make sure you make allowances for protruding structures, especially in cases where it might cross over to your neighbour’s yard.

  • Downpipes - Take into account the placement of your pipes and drainage so you don’t run into trouble during rainy weather or storms.

  • Accessibility - The garden shed and the surrounding area should be accessible in multiple ways for ease of access.

  • Doors - Consider which way you need the doors to open. They can be set to swing either inwards or outwards.

  • Height - If you want to store stackable equipment or mount big items like bicycles, your garden shed needs to have enough height to properly place them.

  • Placement - If the structure is built against the house wall, make sure there is no way water can get between them and cause rotting.
