Nichibei Calculator
Easily calculate tatami costs and the number of louvers! Compatible with smartphones and tablets, so you can use it anytime, anywhere.
Calculate the folding cost of the product, the number of louvers, and the number of slats for some products. It’s a simple operation where you just specify the model and product type and input the dimensions. You can calculate the number of louvers and slats at the same time as the folding cost, so please use it for proposals of mixed louvers or color a la carte. *Please note that the calculation results may have discrepancies from the actual dimensions. Use them as a guideline. *This is applicable to window products (excluding some models), as well as accordion doors and folding doors. *It does not support the roll diameter for roll screen types.
