This site is designed for the trained professional to get information and order their components. A professional can spot the issues and allow for them in the design. Unless you're ordering folding screens or a hanging shoji, the product we sell needs to be measured and installed by a professional.

OK, you're pretty handy with a saw... If you feel confident, measure the top, middle and bottom width of the opening. Next, using a level that is accurate, check the top and bottom horizontal for level, and mark. Using the shortest distance between level marks, and the shortest distance between vertical (sides) of the opening, you now have the basis for correct ordering and installation. 

For smaller projects we recommend you find a reputable finish contractor. For help on designing your home, find an architect or designer who specialize in Asian design. They can help you find craftsmen and women in your area.
