Interior Design Planning: Frequently Asked Questions
How do I calculate paint coverage for a room?
Start by measuring the length, width, and height of your walls. PebasDesign guides break this down step by step, accounting for doors, windows, and coverage per gallon so you don’t overbuy, or run short.
What’s the best way to plan furniture layout?
We recommend starting with room dimensions and flow. By understanding the math behind spacing, you can arrange furniture in a way that feels balanced and practical without wasting valuable square footage.
Why bother with design calculations before starting?
Good design is more than inspiration, it’s preparation. Calculations save money, reduce material waste, and ensure the finished space looks and functions the way you envisioned.
How can I figure out how much flooring I need?
Measure the length and width of each room, multiply to get the square footage, and then add 5–10% extra for cuts and waste. Our flooring guides explain how to adjust this number depending on tile patterns, wood planks, or carpet rolls.
What’s the easiest way to plan lighting in a room?
A simple rule is to multiply a room’s length by width to get square footage, then use 20 lumens per square foot as a starting point. PebasDesign lighting calculators show you how to translate that into real fixture placement.
Do I really need to measure everything before starting a project?
Yes, measure twice, cut once. Accurate measurements upfront reduce mistakes, keep costs predictable, and make sure your finished project fits your vision. Even small errors can add up quickly in time and money.
PebasDesign combines the precision of interior design calculations with the creativity of interior design planning. Whether you’re calculating materials, mapping out lighting, or arranging a small space, our design planning guides make every step simple and reliable. By focusing on smart home design planning, we help you get it right the first time, saving money, reducing waste, and creating spaces that work as beautifully as they look.
