Whether the entrance door is higher or lower than the bedroom door depends on feng shui.

When you build your own house, you'd better make the entrance door higher and bigger than the bedroom door. From the perspective of geomantic omen, the entrance door is the entrance for your whole house to receive water and welcome money. If it is small, it is meaningless for Feng Shui wealth to enter the house. The size of the door is also needed. You can buy a special tape measure to measure. Since you believe in this and pay attention to geomantic theory, you'd better know it clearly before you do it, and don't make mistakes because you don't understand it.
