Measure your complete vehicle before a Stena ferry booking

Describe the vehicle in its travelling form

Make a list of the vehicle itself and everything that changes its outside dimensions: roof bars, loaded cycle carriers, a box, a trailer or another rear attachment. Distinguish between equipment you might take and the arrangement you have decided to use. The dimensions in a handbook usually describe the standard vehicle, not the fully prepared holiday setup. If you are still choosing a carrier, settle the configuration before booking or confirm how a later change would be handled.

Measure rather than estimate the added height

Park safely on level ground and measure the full height using a method that does not require an unsafe climb. A tape measure is useful, but the measurement needs to reach the highest fitted point accurately. Include the actual loaded arrangement where relevant, not just the empty rack. Record the result in the unit required by the booking form. If you cannot measure safely or confidently, seek help rather than rounding down to fit a category that appears convenient.

Check length and width as separate questions

A roof attachment may affect height while a rear carrier or trailer changes length. Read which dimensions the selected category requires and how the operator wants any trailer entered. Do not combine or separate measurements based on an assumption from a previous booking with another company. Width can also matter for an unusual vehicle or equipment arrangement. Present the complete setup to Stena if the online options do not clearly describe it, and retain the response with your booking details.

Choose the category by its limits

Compare the measured dimensions with the current Stena category definitions, including any stated limits and the treatment of roof boxes or bicycles. A category name such as car is not enough on its own. Check every applicable limit rather than stopping after the height looks acceptable. If a measurement is close to a boundary, confirm the appropriate category with the operator. Do not rely on an anecdote that a similar vehicle travelled previously without anyone checking it.

Review changes before departure

Revisit the booking if you add a carrier, exchange the vehicle or decide to tow something after purchase. An amended configuration may need a different category, and space or booking conditions may affect what can be changed. Check the operator process while there is time to resolve it rather than waiting until check-in. Keep a simple note of the vehicle dimensions and registration used. If a hire vehicle is involved, explain the uncertainty to the operator instead of entering an invented exact model.

Use the measurements throughout the road journey

The completed height and length are useful beyond the ferry form. Keep them available when assessing car parks, height barriers and other route restrictions, while observing the signs and rules at each location. Do not treat acceptance onto a ferry as confirmation that every road or car park on the trip suits the vehicle. At the port, follow staff directions and the marked lane for your booking. Leave time to discuss any genuine discrepancy before the departure deadline, without assuming it can always be corrected on arrival.

Your next steps

• Measure the vehicle with its final attachments.
• Check height, length and any applicable width limit.
• Use the current category definitions for the booking.
• Amend the booking if the travelling setup changes.
