Choose the right interactive whiteboard size based on room size, viewing distance, number of participants, installation height, and collaboration needs.
For small rooms, 55-65 inches is usually enough. For classrooms and medium meeting rooms, 75-86 inches is more comfortable. For training rooms or lecture spaces, consider 86-98 inches.

Before buying, confirm wall strength, mounting height, power location, HDMI/USB access, wireless casting support, and whether a mobile stand is required.
