Why Your Square Footage Is Lying to You
Think paint calculation is just length times width? Think again. Discover the three 'hidden' factors—wall texture, color change, and paint quality—that can dramatically alter your paint needs. Stop guessing and start planning like a pro.
It's More Than Just Area
Most paint cans say a gallon covers about 400 square feet. So, you measure your walls, do some quick math, and head to the store. Sounds simple, right? But if you've ever ended up with a half-used can or had to make a frantic mid-project paint run, you know the truth: **square footage is only part of the story.**
Your walls have unique characteristics that a simple area calculation completely ignores. These details are what separate a frustrating project from a flawless one.
Factor 1: The 'Thirsty' Wall - Texture Matters
Imagine watering a smooth pane of glass versus a dry sponge. Which one soaks up more water? Your walls are the same. A brand-new, smooth-as-glass drywall surface is predictable. But an older, porous plaster wall, or a heavily textured surface like knockdown or popcorn ceilings, is 'thirsty.' It will literally drink up paint, easily requiring **10-25% more** than a smooth wall of the same size. Ignoring texture is the fastest way to run out of paint unexpectedly.
Factor 2: The Color Challenge - Going from Dark to Light
Covering a dark navy blue with a light, airy beige is a classic painting challenge. The dark color will try to peek through, forcing you to apply coat after coat of your expensive topcoat. This is where a high-quality, tinted primer becomes your best friend. While it's an extra step, one coat of primer and two topcoats is almost always cheaper and more effective than four or five coats of just the topcoat. A dramatic color change demands a smart plan, not just more paint.
Factor 3: The Paint Itself - Quality Over Quantity
It can be tempting to grab the cheapest paint on the shelf, but this is often a false economy. Lower-quality paints contain fewer solids (the actual pigment and binders that stay on the wall) and more water. This means you need more coats to achieve the same coverage and durability as a premium paint. A high-quality paint might cost more per gallon, but its superior coverage often means you buy fewer gallons and spend less time painting.
Stop Guessing, Start Calculating Accurately
So, how do you account for all these variables? You don't have to. Our **free AccuCoat Paint Calculator** is designed to think like a professional painter. It asks about your wall's texture, your old and new colors, and more. It does the complex thinking for you, so you can walk into the store with a shopping list you can trust.
