What is a board?

A blackboard is a flat surface that receives a special paint that can be black, green or white where you can write or draw using chalk or markers.

They are also known as blackboards as the first models were made of a thin layer of dark slate. Since then the blackboards have evolved to the models we know today.

It is now even possible to find digital blackboards that are touch sensitive and have many of the functionalities of a common computer, such as the ability to save the content used and even surf the internet, making learning much more fun.

Did you know that the first records of the use of blackboards come from India, where they were already used in the 11th century?

What are the different types of boards?

The most traditional models are still the old blackboards, which in fact are mostly the greenboards, which use chalk, are cheaper and easy to maintain.

Whiteboards and glass slates use removable markers and are easier to clean, are in an intermediate price range and offer greater visibility and durability.

But if you want a modern and fully computerised model, for a little more money, you can use digital whiteboards, which are completely interactive. To understand better, see the table below.

However, there are also some disadvantages. In models that work with chalk, the dust that forms when cleaning can be harmful for people with allergies or respiratory problems.

With continuous use, chalk can also dry out the hands and cause cracks. An option to this are whiteboards or glass boards, but they require special markers. For more details, check our table.

Buying criteria: What to consider before buying a board

Blackboards are widely used in school environments, to make it easier for students to view information, to help develop projects in corporate environments and are excellent for menus or advertising promotions in retail.

However, before buying your blackboard, it is important to observe some criteria so that you choose the right model and that offers more cost/benefit to your activities.

  • Material
  • Size
  • Colour
  • Additional Functionality (magnetic)

Take a close look at each of these topics to choose the best board for your education, your business or even to decorate your home with a more interactive touch.


The blackboards can be made of different metals. Even today it is possible to find wooden models, but the most common is that they are made of MDF, a type of plywood which is lighter and cheaper.

It is also possible to find models in plastic, such as PVC, or in metal, the most common being aluminium. You can even find slates made of glass, adhesive or in the form of wallpaper.

The size of the blackboard is also a very important criterion when buying. If you intend to use them in a very large environment, a bigger blackboard will make it easier to see and the amount of information that will be available to the spectators.

Smaller blackboards are ideal for commercial environments, to announce promotions or menus. They can also be used at home, especially for children’s entertainment.

For decorative use, you can choose the size you want, depending on the size of the surface where you want to place it.


When the blackboards first appeared, it was most common for them to be black, grey or green, as this made it easier to see the information using white chalk, creating an excellent contrast.

Today it is possible to find whiteboards, which are brighter. In addition, they can be used with coloured markers, so you can highlight different types of information.

Additional features

With the evolution of blackboards, they have gained some additional functionalities. In metal models, for example, they can be magnetic, where you can use small magnets to attach additional information.

On digital whiteboards these functionalities become even more evident as, in addition to displaying information, they can interact with interactive applications and connect to the internet, transmitting the information directly to one or more computers.

This is transforming ordinary whiteboards into amazing learning and working tools.
