Choosing the Right Size Storage Unit When Moving House

Moving house comes with a lot of decisions. Whether to use self storage or not is one of those decisions. Being unfamiliar with self storage, many families struggle with the question of “What size storage unit do I need for moving house?” If you lease too small a space, your valuables won’t fit. If the space is too big, your moving expenses needlessly increase.

Why Storage Units Are Useful When Moving House

Using self storage when moving home gives you the flexibility to manage your move on your own time. If your move-in and move-out dates don’t quite align, our storage spaces allow you to bridge that gap stress-free.  

Self storage is also a smart way to declutter your home before putting it on the market, so that potential buyers can see your house at its best. Plus, placing bulky items into storage ahead of time makes your actual moving day much easier and more organised. 

What Factors Determine the Right Self Storage Size?

Here’s how to decide what size unit you’ll need during your house move.

How Many Bedrooms Your Home Has

Use your current home size as a rough guide to storage unit sizes when moving.

o Studio flat: 25–35 sq ftOne-bedroom flat: 50–65 sq ft

o Two-bedroom home: 80–100 sq ft4

o Three-bedroom home: 100–150 sq ftFour-bedroom+ house: 160–200+ sq ft

This gives you a ballpark idea when choosing the right storage unit size for your move.

How Much Furniture and Bulky Items Do You Have?

The number and size of furniture pieces will heavily influence what unit size you need. If you have large wardrobes, bed frames, dining tables or family-sized appliances, you may require a larger unit.

Don’t forget to factor in the height of the storage unit. Remember that you can stack items vertically (with care) to save on floor space when you use Storage Vault moving house storage.

Do You Need Access to Your Storage While Moving?

If you’ll need to grab things during your move, plan for easy access. It’s a good idea to leave a central aisle in your unit, especially if it’s larger. This makes it easier to reach items stored at the back. A fully packed unit may look efficient, but it becomes difficult to access anything without unloading everything first. Space for an aisle is particularly helpful when storing bulky furnishings or heavy boxes.

Short-Term vs Long-Term Storage

Even if you’re only planning on using short-term storage during your move, give yourself some flexibility. Unexpected delays, extended renovations or timeline changes are common. A slightly larger unit can give you breathing room and prevent the hassle of having to move everything into a new space mid-process.

You can take some time and get familiar with your new space. Many of our customers end up using our long-term storage options when they realise the convenience of it. Not to mention all the extra space they have at home.

Tips for Choosing the Right Storage Unit

Here are some expert tips to make your decision on “What size storage do I need when moving home?”.

Take an Inventory of Your Belongings

Write down everything you plan to store. Group items by category, e.g. “Furniture”, “Electronics”, etc. Having a clear inventory helps you visualise the space you’ll need and prevents underestimating or overestimating the size of the storage unit you need to move all your belongings.

Use a Storage Size Calculator

Most professional storage providers, including Storage Vault, offer online storage calculators. These tools are designed to help you match your list of items to the right-sized unit, taking the guesswork out of how to pick the right size storage when relocating. Simply navigate to your closest Storage Vault and browse our units.

Visit the Facility and See Units in Person

Whenever possible, pop by your local Storage Vault site. Our team will show you different units so you can get a real feel for the space. Seeing the height and width in person helps you decide what storage size you need for a house move and can often change your mind about what’s truly sufficient for your belongings.

Allow Extra Space for Easy Access

If you’ll need to reach certain boxes during storage, allow a bit of extra room in your unit layout. This is especially important for longer stays. Make sure your most-used items are stored at the front and that you can comfortably move through your unit if needed.
