Last updated: 2 October 2026. These terms apply to WhatSizeStorage.co.uk.
Using the tool
You may use the free calculator and guides for personal or business storage planning. You remain responsible for accurate inputs and checking the actual storage unit, access route and provider’s rules before renting.
Estimates and reliance
Results are approximate planning information. They are not a storage offer, professional survey, loading plan, price quote or guarantee that an item or load will fit safely. Representative dimensions and packing assumptions may differ from your belongings.
Safe storage
Follow provider and manufacturer requirements for prohibited goods, weight, stacking, handling and environmental conditions. Do not place heavy items on fragile furniture or build unstable stacks because a calculator suggests spare volume.
Availability and updates
We may improve or correct the tool. We aim for accuracy but cannot promise continuous availability or that every possible storage arrangement is modelled. You may print an estimate for your own records.
Acceptable use and content
Do not disrupt the site, misrepresent results as a guarantee, or use its content to imply an endorsement. Original site content and calculator code belong to their respective rights holders. Ordinary links to the site are welcome.
Liability and legal rights
To the extent permitted by law, we are not responsible for rental choices or losses arising from reliance on an approximate estimate. Nothing excludes liability that cannot lawfully be excluded or affects applicable statutory rights. These terms are governed by the law of England and Wales, subject to any mandatory consumer protections that apply.
