FAQs
What is the standard whiteboard size?
Common sizes: 3'×4' (office), 4'×6' (medium classroom), 4'×8' (large classroom), 4'×12' (lecture hall). Choose based on room size and viewing distance. Minimum 3'×4' for meetings, 4'×8' for classrooms of 25+ students.
How much does a whiteboard cost?
Basic melamine boards: $30-100 (3'×4'). Porcelain/ceramic boards: $150-500 (4'×8'). Glass boards: $400-1,500 (4'×6'). Installation adds $100-300. Quality affects longevity - porcelain lasts 10-20 years vs. 2-5 for melamine.
What is the best whiteboard material?
Porcelain (ceramic steel) is best: durable, no ghosting, lasts 20+ years. Glass boards look modern, never ghost, but cost more. Melamine is budget-friendly but ghosts after 2-3 years. For daily use, choose porcelain.
How high should I mount a whiteboard?
Mount with the center at eye level. For adults (offices): 4.5-5 feet to center. For children (elementary): 3.5-4 feet. Bottom edge should be reachable - typically 2-3 feet from floor. Leave space below for cleaning and storage.
How do I prevent whiteboard ghosting?
To prevent ghosting: clean daily with proper cleaner, erase immediately after writing, use quality markers, deep clean weekly with whiteboard cleaning solution, condition surface monthly, and replace melamine boards every 3-5 years.
What is the viewing distance for whiteboards?
Viewing distance rule: 1 inch of letter height for every 10 feet of viewing distance. For a 20-foot classroom, write 2-inch tall letters. Maximum viewing distance is 2× board width. A 4' wide board works for rooms up to 8 feet deep.
