The entire experience of the Mystery Spot in Santa Cruz, California, is premised on the fact that the flooring and surrounding environment is uneven, creating the feeling of defying gravity and standing at impossible angles. If only they had a level when they built the place. Of course, it won’t be very exciting for tourists anymore. But the very existence of the Mystery Spot and the many similar roadside attractions are a reminder of the importance of having the best level. Why? Because humans have a pretty good perception of symmetry and evenness. Whether you’re putting up a photo or some shelving, even the slightest degree of asymmetry can be a huge eyesore. And of course, if you’re in construction, ensuring level results are important for more than just aesthetics.
What to Consider Before Buying a Level
The purpose of a level is pretty self-explanatory. Levels measure how parallel a surface is relative to the earth. The way this is accomplished varies by tool. A spirit level (also called a bubble level) is what you probably imagine when you think of a level, and it’s the tool that’s most practical for the average homeowner. A spirit level has a liquid with an air bubble in it, and two lines marked on the glass. When the bubble is between the lines, the surface is level. A spirit level is so named because the liquid inside the vial is typically alcohol. However, spirit levels are not the only options. There are also laser levels and digital levels.
Laser levels shoot out a visible beam that can be helpful if you need to draw a line for your working area. Within this category, there’s a lot of variety, such as more affordable lasers with spirit levels, as well as more expensive self-leveling laser levels that can project horizontal and vertical beams. These automatically level, meaning you don’t need someone to hold it while you work. Finally, digital levels show a numeric value, eliminating human error. These are more expensive, but they’re highly accurate.
How We Chose the Best Levels
Accuracy is probably the most important factor when looking at levels, but accuracy means something different to the renter who’s hanging up a photo than it does to the contractor who’s building the second floor. Digital levels offer great accuracy and convenience, but they can cost hundreds. A good spirit level might only set you back a few bucks, but you won’t get the reliability and legibility of a numeric value. That’s why we picked out a range of options with different features at a variety of price points to meet your needs, whatever they may be. These are the levels to buy.
