A Simple Sizing Guide

If you are staring at an empty wall wondering what size whiteboard to buy, you are asking the right question first. Get the size right, and the board earns its place for years; get it wrong, and it either crowds the room or leaves half your team squinting from the back. The good news? Choosing a whiteboard size is easier than it looks once you know two things: how far away people will sit, and how much wall you have to work with. This guide walks through both, then points you to the standard whiteboard sizes we stock and the custom options we build.

The Short Answer: The Most Common Whiteboard Size

For most classrooms, offices, meeting rooms, and shop floors, the most popular whiteboard size is 4×6: that is, 4 feet tall by 6 feet wide. It gives you a real working surface yet fits a standard wall without dominating it. The next step up, 4×8 feet, is just as common in conference rooms and busy classrooms where more people need to read along. If you are choosing a board specifically for a school, see our guide to the standard classroom whiteboard size. A quick word on how we write whiteboard dimensions: the first number is the height and the second is the width. So a 4×6 board is 4 feet high and 6 feet wide. If you prefer metric, a 4×6 board is roughly 1.22 x 1.83 meters and a 4×8 board is roughly 1.22 x 2.44 meters.

How to Choose the Right Whiteboard Size

Whether you call it a whiteboard size or a white board size, the same three factors decide it:

• Viewing distance: the farther back your audience sits, the bigger the board needs to be. A good rule of thumb: people should be able to read normal handwriting from anywhere in the room. In a large classroom or lecture hall, that usually means going bigger than you first expect.
• Wall space: measure the open wall, then leave a margin so the frame is not jammed against a door, light switch, or corner. Give yourself a few inches of breathing room top and bottom, and account for the marker tray. Once you have the size picked out, our guide on how to hang a whiteboard walks through installation.
• How the room is used: a brainstorming team that fills a board fast wants more surface than a small office jotting a few reminders. When in doubt, size up; unused board space is never the complaint we hear.

For classrooms in particular, placement matters along with size. See our recommendations for the best mounting heights for classroom whiteboards.

When to Go Taller: Boards That Are 5 Feet Tall

Standard boards are 4 feet tall, which suits most rooms. But if you are outfitting a lecture hall, a large training room, or any space where people sit far from the wall, consider a board that is 5 feet tall. That extra foot gives you about 20 percent more writing surface, so presentations can be larger and easier to read from the back rows. Our 5-foot-tall boards are built for exactly that. If you need even more writing room, see our guide to large whiteboard options. If the board will double as a projection screen, a low-glare surface made for projection is worth a look too.

What About Custom Whiteboard Dimensions?

Sometimes the wall simply does not match a standard size, and that is fine: because we are the manufacturer, we cut boards to the whiteboard dimensions you need. Custom size boards are available with aluminum or wood frames and with magnetic or nonmagnetic surfaces. If you need a custom board between 1 and 5 feet tall, fill out our custom size request form with the height and width in inches. For boards taller than 48 inches, or cut in a shape that is not rectangular or square, call us at 1-800-335-7319, and we will build it to spec. Not sure which board dimensions fit your space? Send us your measurements through our quote request form, and we will help you get it right the first time.

Whiteboard Size FAQs

What is the standard whiteboard size?

The standard whiteboard size for most classrooms and offices is 4×6 feet, which is 4 feet tall and 6 feet wide. It offers a generous writing surface while fitting a typical wall. Conference rooms and larger classrooms often step up to 4×8 feet for more space and better visibility.

What whiteboard sizes are available?

EVERWhite offers 15 standard whiteboard sizes, ranging from a compact 1×1 foot up to an expansive 4×20 feet. Popular options include 2×3, 3×4, 4×4, 4×6, and 4×8 feet. If none of the standard dry erase board sizes fit your wall, we also build custom sizes to your exact dimensions.

How do I choose the right whiteboard size?

Start with viewing distance and available wall space. The farther your audience sits, the larger the board should be so writing stays readable from the back. Measure your open wall, leave a margin around the frame, and size up if your team fills a board quickly. When in doubt, bigger is better.
