Tools to help accurately measure a room for painting
Now that you have an idea of what you’ll be measuring, you’ll need to figure out how best to measure each surface. Here’s some options when measuring for accuracy.
A tape measure is a flexible metal strip used to help you accurately measure surfaces of various sizes. The tape is held within a plastic holder, which allows you to easily pull out the amount of tape needed and have it easily retract back in for storage. Tape measures also have the ability to lock in place and most have a metal hook on the end, allowing for more precise measurements.
Tape measures are really helpful when measuring for a paint job, as they’re easy to manipulate and easy to use with your hands. They also provide an easy way to get exact measurements of all the surfaces you wish to paint.
Laser tape measure
A laser tape measure is an electronic device that allows for accurate measurements using a laser pointer. To use, simply place the device where the surface begins and allow the laser to bounce off an object (ie. wall, door, physical target) on the other side. The device will then display the length on a screen.
Laser tape measures are great to use for measuring because they aren’t as physically strenuous and have shown to give very accurate readings. They’re also great for measuring on your own and in a hurry. If you’d like to opt to use this method, there are many great devices to choose from.
Calculation and data storage
After all your hard work measuring, the last thing you want to do is lose or mix up all of your measurements. Making a habit of recording all of your measurements will make sure you don’t have to do everything twice, and it will allow for easier calculations later on. Pencil and paper is an easy way to go if you just want a quick record of your measurements, but you might want to consider going the digital route instead.
Using programs such as Google Sheets or Microsoft Office Excel will help you make sure that your measurements are never lost, and that your measurements are all attributed to the correct surfaces. Plus, their quick and easy calculation features will help you do your math faster and more accurately, so your contractors will have the proper numbers to work with. An added bonus is that you’ll be able to store your documents on your phone, allowing you to pull up your measurements while on the go.
How to Measure Walls with Doors and/or Windows
If there are any obstacles on your wall, such as doors or windows, simply measure the entire wall as you would for a full standard wall and cut away the obstacle during hanging.
As a precaution, we also suggest you add 5cm or 2” to your overall dimensions. This can be trimmed off once your mural is installed.
How to figure square footage of a wall?
It doesn’t matter whether you’re thinking how to calculate wall square footage for paint or for wallpaper – it’s the same. Use these pieces of advise to improve your ability to figure out the square feet of your wall:
Precise measurement is the key 🔑 – no matter if you’re using the wall sq ft calculator or computing everything yourself:
Start with drawing a plan of your room/house – it’ll make it easier to measure and store data;
Alway use the proper equipment – a steel tape measure or a yardstick;
Measure the length of your walls, including both doors and windows; and
Determine the height of your walls – measure them from the floor to ceiling. Exclude the length of a dropped ceiling or moulding (coving).
It’s math time! Let’s find out how to calculate the square feet of a wall.
So how do we calculate the square feet of a wall? The equation is simple:
walls square footage = total length of the walls * ceiling height
But how to calculate sq ft of a wall with doors and windows? 🤔
corrected wall square footage = wall square footage - windows area * number of windows - door area * number of doors
Now it’s time to figure out the square feet of windows and doors – take a look at the standard sizes, presented in the table below:
|Windows||3 x 4 ft||12 ft²|
|Doors||3 x 7 ft||21 ft²|
That’s how to calculate square feet of a wall. Are you still at the beginning of your journey, not yet sure about the number of planned doors and windows? Try our basic construction calculators:
