In this blog, we'll explore the ideal storage unit size for a three bedroom house, helping you find the right fit for your belongings with practical tips and guidance.

Moving house can be an exciting but challenging experience, and the process often involves finding the right self storage unit. You might be asking yourself: what size storage unit do I need for a 3 bedroom house?

That question is perfectly understandable, especially when you’re juggling large furniture, kitchen appliances, wardrobes and all the miscellaneous items accumulated over the years.

We know it’s easy to underestimate how much space you need, leading to renting the wrong size and having to shift all your belongings again.

Below, we’ll walk you through common unit sizes, share tips for picking the perfect storage space, and explain how to ensure your belongings remain safe, even if you’re dealing with fragile items and delicate items.

We’ll also let you know how to handle packing efficiently, so you won’t spend hours rummaging through boxes later on.

Understanding your storage needs

Moving house boxes

Your first step is figuring out how much storage you actually require. Most people look at their three bedroom house and assume a smaller unit might do the trick, only to discover their space is quickly maxed out.

Nobody wants to face the hassle of upgrading from a 75 sq ft to a 150 sq ft unit mid-move, so it’s best to get it right from the beginning.

Assessing how much space you really need

The typical 3 bedroom house can hold a surprising amount of belongings.

Even if your furniture and appliances don’t seem excessive, once you start packing wardrobes, kitchen appliances, and large furniture such as a dining table or sofas, you’ll quickly see how much storage is needed.

A storage size estimator or storage size calculator is often a good place to start. These tools help you visualise the number of boxes and large items you’re storing, ensuring you select the right size storage unit.

By considering how much space your belongings will occupy and factoring in a bit of extra space to move around, you can avoid renting a unit that’s too small.

Smaller unit vs. slightly larger unit

You might be tempted to get a smaller unit to cut costs. However, if it’s too cramped, you risk having to rent another or move up to a larger space.

Choosing a slightly larger unit from the start can save you time, money, and energy in the long run.

Ask yourself:

  • Do I have big-ticket items like a dining table or large furniture?
  • Will I be storing items from a double bedroom or more than one?
  • Is there a chance I’ll be adding more belongings to the 3-bedroom house later (especially seasonal decorations or fragile items)?

If you answered “yes” to any of these, go for a unit that can comfortably handle your belongings without forcing you to play an endless game of Tetris.

Practical storage tips

Plan your packing in advance

Packing is about more than bubble wrap and boxes. Think strategically about how to arrange your belongings so you don’t run out of storage space. A detailed storage size guide can help you figure out how much storage you need based on each room in your house.

Aim to

  • Disassemble beds and tables to create more space inside your house or self storage unit.
  • Use bubble wrap, protective blankets, and cardboard corners for fragile items to prevent damage.
  • Keep heavy furniture at the bottom and stack lighter or smaller items on top.
  • Label your boxes clearly so you can find everything quickly if you need to retrieve it later.

If you need to stock up on packing supplies like bubble wrap or sturdy boxes, pop by our box shop so you’re well-prepared.

Moving house logistics

Should you hire a removal company?

It often makes sense to hire a professional removal company to load and transport your furniture to your chosen storage unit.

They’re used to moving heavy items like wardrobes and can reduce the risk of damage to delicate items.

If you’re a fan of doing it yourself, just remember to compare the capacity of a small van, transit van, or Luton van to ensure you can transport your stuff in a single trip.

Planning your route

When moving house, plan your route to the storage site.

A large Luton van or transit van might need extra space for manoeuvring, so check that the roads and driveways leading to the storage company can accommodate larger vehicles.

This foresight will reduce stress on moving day and help ensure your items make it from your house to the storage unit smoothly.

Avoiding the wrong size

The risk of picking the wrong size is that it wastes time, money, and effort. A storage size guide is a great tool for visualising what can fit into 25 sq ft, 75 sq ft, 150 sq ft, or anything in between.

Hand taking something out of box

If your current house is bursting with boxes or your wardrobes are overflowing, don’t underestimate your storage do I need calculations—choose a size storage unit that’ll comfortably fit your belongings.

Here are some key pointers to help you decide:

  • Use a storage size calculator or storage size estimator to gauge how much space your items require.
  • Factor in future storage needs, like seasonal decorations you might add in autumn or winter.
  • Consider slightly larger unit sizes if you’re close to maxing out the capacity.

Extra tips for a smooth move

Use the right packing materials

Saving a few pounds by reusing old supermarket boxes can be tempting, but weak boxes might split, damaging your fragile items or your unit’s floors.

Quality boxes and bubble wrap will keep everything safer. Our box shop offers robust options so you can protect your belongings properly.

Stack cleverly

You can gain more space in your self storage unit by stacking items vertically, but be mindful of what goes on top of what.

Heavy boxes should form the base, with lighter boxes above them, to avoid crushing anything delicate.

Label everything

When you’re moving house, it can be easy to lose track of what’s in each box. By labelling your boxes on all sides, you’ll know exactly where your bedding, small office supplies, or kids’ toys are stored.
