# Roof Box & Rack > Roof Box & Rack is a UK publication covering roof boxes, roof bars, bike and watersports carriers, fitting, loading, travel and equipment care. Guides compare manufacturer dimensions, fitting instructions and primary sources linked within the articles. Original calculations explain how published specifications affect packing and load decisions. Generated editorial photographs illustrate situations and do not certify a fit. Vehicle compatibility requires the exact vehicle handbook, approved complete rack and equipment instructions. The roof-load calculator compares entered weight limits; it does not approve a fit. Dimensions, empty weights, kit contents and mounting restrictions refer to the exact model or variant discussed. Product availability can change; check the current listing and manufacturer instructions. The linked HTML pages contain the full advice, comparison tables, worked examples, FAQs and sources without requiring JavaScript. JavaScript adds the interactive tools and authorised Amazon product images. This index supplements the sitemap; robots.txt controls crawler access. ## Starting points and tools - [Homepage](https://roofboxandrack.co.uk/): Choose a carrying task and use the setup finder. - [Roof boxes](https://roofboxandrack.co.uk/roof-boxes/): Capacity, shape, weight, access and buying decisions. - [Roof-box comparison](https://roofboxandrack.co.uk/best/roof-boxes/): Exact shortlist variants, dimensions and practical trade-offs. - [Roof bars](https://roofboxandrack.co.uk/roof-bars/): Complete systems, feet, fitting kits and roof types. - [Fit and roof-load calculator](https://roofboxandrack.co.uk/fit-load/): Vehicle fit, clearance, journey planning and separate weight limits. - [Bike and sports carriers](https://roofboxandrack.co.uk/carrying/): Bikes, kayaks, canoes, boards and winter equipment. - [Packing, storage and care](https://roofboxandrack.co.uk/storage/): Bags, restraints, off-car storage, replacement parts and maintenance. - [All guides](https://roofboxandrack.co.uk/guides/): Human-readable directory of the detailed articles. - [Fit and troubleshooting help](https://roofboxandrack.co.uk/help/): Routes into common fitting and equipment problems. ## Choosing and owning a roof box - [What Size Roof Box Do You Need?
