How to Read Your Spirit Level

Using a spirit level is essential for ensuring that surfaces are perfectly horizontal or vertical. But how do you read the bubbles on the spirit level to know if it’s in the right position? It’s not as difficult as it seems! In this article, we’ll show you exactly how to use and read your spirit level so that you can get accurate results every time.

With these simple steps, you’ll be able to check if any surface is perfectly flat or square with ease. So let’s get started and learn how to read your spirit level!

Calibrate Your Spirit Level


To begin, you’ll need to calibrate your spirit level. This is done by placing the bubble at the center of the vial. To do this, you can use a standard square or carpenter’s ruler and gently move the spirit level from side to side until it seems centered in between both ends of the vial.

Place it On Any Surface

Once your spirit level is calibrated, simply place it on any surface that needs to be checked for levelness or plumbness. The bubble should rest either in the middle (level) or off-center (plumb). If it’s off-center, then you’ll need to adjust whatever it is that you’re trying to build so that is properly aligned. The further away from center that¬† the bubble is, the more off-level or off-plumb your surface is.

Are Digital Levels Better Than Traditional Ones?


It’s a question of personal preference. Digital levels are often more precise than traditional spirit levels, and they come with many features that can make it easier to read the level. They are also less prone to wear or damage over time, making them a better long-term investment. On the other hand, traditional spirit levels require less calibration and may be easier for some users to interpret when reading the measurements.

It is up to you as the user to decide which type of level best suits your needs and preferences. Whether you choose a digital or traditional spirit level for your next project, understanding how to read your chosen one will help ensure accuracy in all your work.  Remember: accuracy is key! Happy measuring!

Why are Some Bubbles in the Tube of the Spirit Level Bigger Than Others?


The size of the bubble inside the tube is determined by how level the surface is. A larger bubble indicates that the surface is more level, while a smaller bubble indicates that it is less level. When you are using a spirit level, it’s important to make sure that the bubble falls exactly in between two marks on the tube, indicating that the surface is perfectly level.

If the bubble falls to one side or another, this means that there may be an unevenness in your surface and further adjustments should be made. With practice and patience, you can learn to read even small differences in size between bubbles.


Using a spirit level may seem daunting at first, but with a little practice you’ll be able to use it like a pro! Just remember that accuracy is key when using a spirit level and always make sure to properly calibrate it before each use. With these steps in mind, you’ll have no problem correctly reading your spirit level.
