Whiteboard Sizes in South Africa: The Complete Guide (2026)

Choosing the right whiteboard size is the difference between a board that gets used every day and one that is either too cramped to be useful or too large for the wall it hangs on. This guide covers every standard whiteboard size available in South Africa, what each size costs, and which size suits which space. All boards listed here are manufactured by Bestboard in Johannesburg and available nationwide.

Quick answer: standard whiteboard sizes

Standard wall-mounted whiteboard sizes in South Africa range from 450mm x 600mm (the smallest framed board) up to 1200mm x 3000mm (a full three-metre board for lecture theatres). The most popular sizes are 900mm x 1200mm for home offices and small meeting rooms, and 1200mm x 2400mm for classrooms.

Which whiteboard size do I need?

Home office or study: 450mm x 600mm to 900mm x 1200mm

For a desk-side board used for daily task lists and reminders, the 450mm x 600mm is compact and affordable. If you run video calls, plan projects, or teach online from home, step up to the 900mm x 1200mm. It gives you enough space to work through a problem without wiping every few minutes, and it still fits comfortably on most home office walls.

Office and meeting rooms: 900mm x 1200mm to 1200mm x 1800mm

The 900mm x 1200mm is the most popular size in South African offices for good reason: it suits a small meeting room for 2-6 people. For boardrooms or rooms where the board anchors the meeting, the 1200mm x 1800mm gives presenters room to keep earlier notes visible while adding new ones.

Classrooms: 1200mm x 2400mm to 1200mm x 3000mm

Classroom boards need to be readable from the back row, which means both height and width matter. The 1200mm x 2400mm is the standard South African classroom size. For lecture theatres and large training halls, the 1200mm x 3000mm provides a full three metres of writing surface.

A useful rule of thumb: the furthest viewer should be no more than six times the board height away. A 1200mm high board is comfortably readable from about 7 metres, which covers most classrooms.

Training rooms: 900mm x 1800mm or a mobile whiteboard

Training rooms benefit from wide-format boards like the 900mm x 1800mm, or from mobile whiteboards on castors that can be repositioned as the session demands. Mobile boards are available in single sided and double sided versions, magnetic and non-magnetic, in sizes from 900mm x 1200mm up to 1200mm x 2400mm. Double sided models effectively double your writing surface: flip the board instead of erasing.

Magnetic vs non-magnetic: does it change the size decision?

No. Both ranges are available in the same core sizes, so choose the surface type based on how you work, not on size availability. Magnetic whiteboards let you pin documents, printouts, and magnetic accessories to the surface alongside your writing, which is why they are the standard choice for offices and classrooms. Non-magnetic boards do the same writing job at a lower price in most sizes, and suit spaces where the board is purely for writing.

How to measure your wall for a whiteboard

1. Measure the available wall width and height, and subtract at least 100mm on each side for clearance.
2. Check for obstructions: light switches, plug points, skirtings, and dado rails.
3. Consider mounting height. The vertical centre of the board should sit at roughly eye level for the people using it: about 1500mm from the floor for standing use, lower for classrooms with younger learners.
4. If the wall is drywall rather than brick, confirm the mounting points can carry the board's weight. Larger boards should be fixed into studs or with appropriate drywall anchors.

Do bigger whiteboards need special installation? Boards up to 1200mm x 1800mm are a straightforward two-person installation with the supplied fittings. Larger boards are heavier and longer, so we recommend two installers and fixing into solid brick or into studs on drywall.
