For many people, purchasing a white board over a blackboard is an obvious choice. There are quite a few advantages offered by white boards. However, that doesn’t mean that they are the perfect writing medium for your purposes. Keep in mind the disadvantages that come with using them so that you won’t be in for any unpleasant surprises.
- White boards generally cost more than blackboards of comparable size.
- Using markers that aren’t designed for white boards can result in difficult to remove or even permanent marks. Attempting to remove such marks can damage the board itself, although there are some techniques that are commonly used.
- Some people who are visually impaired have difficulty reading writing on dry erase boards.
- If someone writes left-handed, there is often a problem of smearing the writing that is already on the board. This problem also occurs with chalkboards, however.
- Unlike chalk, it is difficult to tell when a marker is running low.
