The science of blackboard size is coming!

To build a perfect classroom, the size of the blackboard is the key! According to the data of People's Daily Online, the height of the blackboard should not be less than 1000mm, while the width of the blackboard should be at least 3600mm in primary schools and at least 4,000 mm in secondary schools. Only in this way can we ensure that every student can clearly see what the teacher has written.

Position relationship between blackboard and platform

In addition to the basic size, the position relationship between the blackboard and the podium is also very important! The vertical distance between the lower edge of the blackboard and the platform is suggested to be between 800-900mm in primary school and between1000-1100 mm in middle school. This can not only ensure the comfort of teachers' writing, but also make students see more clearly.

Material selection of blackboard

The material of the blackboard cannot be ignored! The surface should be made of wear-resistant and dull materials, which can not only ensure the service life, but also avoid the reflection from affecting the students' sight.

Design of podium and collocation of blackboard

The design of the podium should also consider the collocation with the blackboard The horizontal distance between the two ends and the edge of the blackboard is not less than 200 mm, the width is at least 650mm, and the height is about 200 mm. This design is not only beautiful and elegant, but also ensures that students have enough space when attending classes.
