Is it okay for the photography studio to be 2.5 meters high?

Height alone is not enough. Now many studios are dominated by natural light. The most important thing is the pattern and lighting. Of course, there must be matching and overall effect. If you haven't worked in this field before, I suggest you go to the studio to study first. Don't invest blindly. Now the saturation of this industry is different in every city. You must check the market before you can continue! I hope my answer can help you.
