Car Park Line Marking Best Practice

A well-marked car park does far more than look tidy. It maximises capacity, guides traffic safely, keeps pedestrians protected and ensures you meet accessibility requirements. A poorly marked one wastes space, creates conflict points and can leave you non-compliant. Here's what best practice looks like.

Get the bay dimensions right

Standard UK parking bays are typically around 2.4m wide by 4.8m long, with wider bays for accessible spaces and generous aisle widths for safe manoeuvring. Getting dimensions right balances capacity against usability — cramming in too many tight bays leads to door damage and frustrated users.

Accessible and EV bays

Disabled bays need to be wider with hatched access zones, clearly marked with the wheelchair symbol, and located close to entrances. EV charging bays should be clearly designated near charge points. Marking these correctly isn't just good practice — it's part of meeting your accessibility obligations.

Traffic flow and pedestrians

• Use directional arrows and give-way markings to control flow and reduce conflict.
• Mark clear, protected pedestrian routes from parking areas to entrances.
• Use hatching to keep junctions, ramps and access points clear.
• Define loading, drop-off and motorcycle areas where needed.

Choose materials built for the weather

External markings face rain, frost, UV and standing water. Cheap paint can fade within a single winter, whereas hot-applied thermoplastic and MMA stay bright and sharp for years. Proper surface preparation is essential — markings should never be applied to a wet or contaminated surface. We assess the surface and specify a system that lasts.
