Which Board Thickness Should You Use? 6mm, 12mm, 16mm, 18mm Explained

Choosing the right board thickness is one of the most critical decisions in interior projects. Whether you're working on a modular kitchen, wardrobe, TV unit, or office storage, the wrong board thickness can lead to warping, breakage, or poor finish.

At Khidki Homes, we offer plywood, MDF, and PVC boards in multiple thickness options to suit different applications — all available with 4-hour delivery across Bangalore. Here’s a detailed breakdown of when to use 6mm, 12mm, 16mm, and 18mm boards, based on your project type.
