## How to Calculate How Much Paint You Need for Doors and Trim – Real World Example

here is a real-world example using measurements from my own home. **As you do these measurements in your home, use the exact number or round up. That way you’ll end up with a little extra paint rather than a little less.**

### What You Need

- Tape measure
- Calculator
- Pen and paper to record your measurements

### 1. Measure the length and height of your baseboards.

My home function is 10 feet by 10 feet or 100 square feet. So there are about 40 linear feet of baseboards. The baseboards are three inches grandiloquent, or 0.25 feet. Multiply the entire duration of baseboards, 40 feet, by their acme, 0.25 feet. **This gives you 10 square feet of baseboards.** Mark this number down ( Chances are, yours won ’ thymine be 10 precisely. But it ’ sulfur possible ! ) .

### 2. Measure the length and height of your door.

adjacent, quantify the dimensions of your door. just the door, not the trim. The altitude of the door in my office is 80 inches, and the width is 30 inches. Again, convert these into feet by dividing by 12 for dim-witted measurements. 30 inches / 12 = 2.5 feet 80 inches / 12 = 6.67 feet **2.5 feet * 6.67 feet = 16.675 square feet for your door** circle this number and move on to the future step .

### 3. Measure the length and height of your door trim.

Door trim can be a small crafty to measure but do your best. If in doubt, overestimate. That way you ’ ll end up with more paint than you need. You won ’ t have to go back to the store. first, measure the acme and width of the door trim as it ’ second installed around your doorway. The door pare is 82 ” high on each side and 35 ” wide. Add these three measurements up and divide by 12 to get the total linear feet of shave. 82 ” +82 ” +35 ” = 199 inches. 199 inches / 12 = 16.583 feet. immediately you measure the length of the trim around your door. The tailored in my office is about 10 ” round. You besides have to convert this measurement to feet. 10/12 is about .83 feet. now multiply 16.583 feet * 0.83 feet = 13.82 square feet. **So the total square footage of door trim in this example is 13.82 square feet.**

### 4. Measure the length and height of your window trim.

last on the tilt is window trim. My office has one window. First I measured the length and width of the trim .

- Length: 60”
- Width: 48”

So the entire perimeter of my window trim is 60 ” +60+48 ” +48 ” = 216 ” 216 ” / 12 = 18 feet. The trim on my window is quite thin, at barely 1 ”. Again, commute this to feet. 1 column inch / 12 = .083. **18*.083 = 1.5 square feet for window trim**

This is a negligible amount of square footage. But your trim may be different. So it ’ south authoritative to do all your measurements !

### 5. Calculate how much paint you need for doors and trim.

Using the final examination numbers from each step above, calculate how much key you need for doors and trim. 10 + 16.675 + 13.82 + 1.5 = 42 public square feet. Multiply this number by two to account for a second coat. 42 squarely feet * 2 = 84 square feet Since we know that a gallon covers about 400 square feet, a quart covers one-fourth of that or 100 square feet. **So, to do all the doors and trim in my office, I’ll need a little less than a quart for two coats.** Remember, the best manner to figure out how much paint you need is to do your own measurements. Take a expect at the labels on your paint to see how much squarely footage it covers. Be sure to use that number in your measurements. Divide it by four to get the measure of coverage per quart of key. Take a look at this video below for a promptly retread on how a lot paint you need for your home .
