What is the minimum required clear space under a table for wheelchair users?

The minimum required clear space under a table for wheelchair users is 750 mm. This measurement ensures that individuals who use wheelchairs can comfortably and safely approach and utilize tables without obstruction. The space needs to accommodate the height of standard wheelchairs, allowing for proper legroom and access to the table.

In practical terms, having at least 750 mm of clear space under the table helps provide enough room for the footrests of the wheelchair while also allowing the user to position themselves close to the table's surface. This consideration is crucial for enhancing accessibility and ensuring that all individuals can engage with the space effectively.

The other measurements do not meet the minimum standards for accessibility, as they either provide insufficient space or may create barriers for users with different types of mobility devices. Therefore, the specification of 750 mm strikes a balance between usability and providing adequate space for individuals in wheelchairs.
