20ft vs 40ft Liverpool Storage Units, which size is right for you?

Choosing the right storage container can save you money and make your life easier. Whether you are storing personal belongings or running a business that needs secure space, understanding the difference between 20ft and 40ft storage units helps you pick the right option.

At Tilly Hire we offer both container sizes, and each one suits different types of storage needs.

Here is a simple breakdown to help you choose the right option based on what you are storing, how long you need it for and how often you plan to access it.

What is the difference between a 20ft and 40ft storage unit?

Both container types are built from heavy duty steel, fully weatherproof and designed to keep your items safe and secure. The main difference is size.

20ft container:

• Approx. 33 cubic metres

• Similar to a single garage

• Great for smaller loads, house contents, tools and stock

40ft container:

• Approx. 67 cubic metres

• Roughly two single garages

• Ideal for large volumes, bulky items and long term storage

The internal layout is the same, so it comes down to how much space you actually need.

When a 20ft container is the best choice

A 20ft unit is the most popular size for both personal and business storage. It offers enough space without paying for room you will not use.

Perfect if you are storing:

Personal use:

• Furniture during a house move

• Contents of a bedroom, flat or small home

• Bikes, camping gear, garden furniture

• Seasonal items you do not want cluttering the house

Business use:

• Tools, equipment and materials for trades

• Small stock deliveries

• Archive boxes or paperwork

• Ladders, small machinery or event kit

Why choose a 20ft:

• Cost effective

• Easier to organise and access

• Ideal for short term and medium term needs

• Quick to load and unload

• Great for people who need simple, reliable extra space

If you are unsure how much space you need, a 20ft is usually the safest place to start.

When a 40ft container is worth it

A 40ft container is designed for people or businesses who know they need plenty of room.

Ideal if you are storing:

Personal use:

• Full house contents

• Long term belongings during relocation

• Motorbikes, quads or project cars

• Large furniture sets

Business use:

• Palletised stock

• Long materials like timber or scaffolding

• Machinery or bulky tools

• Event equipment, staging or exhibition kit

• Multiple stock deliveries that need segregated space

Why choose a 40ft:

• Double the floor space

• Suitable for long term storage

• Ideal for businesses with stock changes or growth

• Allows you to consolidate and avoid renting multiple smaller units

• Perfect for bulky or awkward shaped items

If you want to future proof your storage, a 40ft gives you breathing room.

Key questions to help you choose the right size

Before you decide, think about:

1. How often will you access it Daily access works better with clear floor space. If you are stacking items, you may want the larger footprint of a 40ft.

2. Are your items stackable Boxes, tools and small items fit a 20ft perfectly. Large stock, pallets and long items are better suited to a 40ft.

3. Is this personal or business storage Personal storage is often smaller and short term. Business storage tends to grow over time.

4. Will your needs increase If you are expecting stock increases or ongoing home projects, a 40ft might save you moving later.

5. How long are you storing for Short term, a 20ft is often enough. Long term, a 40ft gives more flexibility.
