How to calculate how much storage space


Unless you are a seasoned self-storage expert, trying to decide how much space you need can be a daunting task. If you over-estimate you could end up paying over the odds for storage space you don’t need. Alternatively, if you under-estimate you could in a position where you now need two units, which is generally less convenient and cost-effective than paying for one larger space.

This post explores ways in which you can take out of estimating the size of the space you need.

How to decide how much storage space you will need

Make a list of potential items

First of all, make a full inventory of what you intend to store. You must have some idea of what you need to store, otherwise, you wouldn’t be looking to invest in storage. Make a list of everything you can think of that you may or may not need to keep. Add notes to each item such as "definite”, "potential” or "maybe in the future” so you have an idea of how much your space may potentially need to grow.

How big are the items and how many will you store?

Once you have your list of items, find a decent approximation of how big each item is. For example, if you are storing your furniture, you can usually find dimensions of items online. Check a couple of sources if you have time and record the dimensions on your inventory list multiplied by how many of the items you wish to store.

Do you need racking or shelving?

A further consideration is whether you will have racking or shelving. Calculating the cubic capacity of a space is all well and good if you can stack items up to the roof. Consider whether you will need racking or shelving. This will help you to maximise the space beyond the floorplate of the storage space. Alternatively, in bigger units, a mezzanine floor can be an ideal way to maximise the space that would otherwise be fresh air.

Some rules of thumb

There are a handful of "rules of thumb” that can be applied are as follows. Please note that every need is different so do not accept these as definitive measurements but they can be used as a rough guide in conjunction

  • with our steps outlined above.
  • A set of luggage or storage boxes – a 3 sq. ft
  • A small van load – 20 sq. ft
  • A transit van load – 40sq. ft
  • Contents of a two-bedroom house – 80 sq. ft
  • Contents of a four-bedroom house – 180 sq. ft
