Best Levels of 2021: What to Buy and How to Use Them

Although you might think any level will work for you, the reality is that there are different level types for various construction projects.

Whether you’re licensed as a professional general contractor, electrician, or plumber, you’ll use your level more often than you think. A good level is also among the top tools you’ll need if you’re an at-home DIYer or handyman who’s in the process of remodeling your home.

In this extensive guide, we’ll help you select the best level for your project by simplifying the process and providing all the details you need about each level. We also include budget-friendly options that can help you save money during the remodeling process.

Before diving in and discussing different level types, let’s look at essential insights to help you decide which level is right for you and your project.

Types of Levels

While shopping around, you’ll notice that there are many level types available, each of which is designed for a specific use.

• Carpenter Levels: Frequently also referred to as “bubble” or “spirit” levels, carpenter levels feature a rectangular design as small as 16″ long and as lengthy as 48”. Inside two or more vials, you’ll find liquid with a bubble in the middle, which shows you when you’re level and when you’re not.
• Electronic Levels: Also called digital levels, these models often feature digital displays, some of which even light up, which could come in handy in dim or dark working conditions.
• Engineer’s Precision Level: Engineers and architects use these levels to measure foundations precisely.
• Laser Levels: These levels feature a built-in red laser that can extend up to several hundred feet for working in large spaces. Keep in mind, however, that these lasers can be difficult to see in bright light.
• Line Level: Features a one-bubble design with an overhang that allows you to suspend the level from a string. It’s ideal when building cabinets or installing patios.
• Mason’s Level: Typically at least four feet long, mason’s levels can be used in a wide variety of scenarios, including leveling cabinetry.
• Optical Levels: These level types are often used in construction and surveying, where you need to check levels across long distances, such as an entire construction site.
• Scaffold Levels: Feature magnets can keep the levels in places while measuring scaffolding and plumbers who work with piping and other metal components.
• Surveyor’s Level: Also referred to as “dumpy,” “tilting,” or “automatic,” a surveyor’s level helps check elevations across long distances.
• Torpedo Levels: Small levels that are ideal for moving around in confined spaces, with a tapered end that gives it its namesake. Torpedo levels typically range between 6” and 10” long.
• Water Levels: Suppose you need to match location elevations or work across long distances (such as between two rooms). In that case, water levels feature two cylinders that work based on the fact that water automatically seeks its own story.

Level Features to Look For

Different levels come with various features, so when searching for a level, you’ll want to focus on those most useful to you. Here are some common examples of what you’ll find during your research:

• Accuracy – The longer the level, the more accurate it is. On the other hand, levels with more extended designs can decrease functionality in tight spaces.
• Bubble size and liquid color – Levels with larger bubbles are easier to read from a distance. Most levels are also filled with brightly colored alcohol (usually ethanol) for added visibility. Yellow/green is the traditional color, although you’ll encounter models with red or blue coloring.
• Reading lines – Most models feature lines that wrap around their vials for more precise measurement.
• Construction, protection, and durability – Most professional-grade levels are made from aluminum and built to take regular abuse, whether on a job site or at home. To maximize protection, look for models with shock-resistant corners and vials.
• Thumbscrews – These screws feature flat, rounded, knurled heads you can use to clamp your level to different surfaces.
• Rafter hooks – Although most levels don’t come with them, you can insert yours into l-shaped hooks for measuring rafters.
• Use and grip – Hand notches provide additional grip, which can be extra useful when working with a longer level.
• Lighting and illuminated vials – These levels come with LED-lit vials to help maximize visibility in dark areas.
• V-Groove – These levels look like upside-down V’s, hence their name. They help to level almost any pipe or conduit, whether horizontally or perpendicular.
• Magnetic – These levels feature built-in magnets that allow them to stick to iron-based surfaces.

Best Laser Level: Bosch Three-Plane Leveling Line Laser

While there are many different versions available, laser levels work by casting a built-in laser onto different surfaces (walls, floors, and so forth) that, once appropriately calibrated, can deliver the ultimate ease of use.

And there’s a lot to like about Bosch’s Three-Plane Leveling Line Laser, including high-end features like self-leveling functionality and three different measurement planes, which you can view from up to 330 feet away (the company calls this their VisiMax technology).

The 360-degree Green Beam also connects via Bluetooth and allows you to control the level via a free smartphone app, including:

How to Use a Laser Level

Laser levels are super cool and high-tech, but they’re straightforward to use in a wide variety of scenarios. These include hanging pictures or artwork, leveling floors, aligning shelves and cabinetry, and ensuring walls and other surfaces are plumb.

Briefly, here’s how it works:

1. Turn your level on, which will cast its laser as a line or dot;
2. Set the tool on a flat surface (unless yours features auto-level functionality);
3. Fine-tune and calibrate your level using the bubble, screws, or knobs;
4. Find the beam and align it to your needs (note: this part will be more difficult outdoors, especially in bright sunlight);
5. Take your measurements and repeat.

Best Torpedo Level: Klein Torpedo Bullet Level

A torpedo level features tapered ends that work great for general-duty applications and a compact design ideal for moving around in confined spaces. Klein’s Torpedo Bullet Level (model #935RB) uses four high-visibility, easy-to-read vials, each set at different angles (90, 45, and 30 degrees), for ultimate usability. The level also comes with a patented magnet track that prevents them from dislodging, along with a v-groove for working with pipe and conduit.

How to Use a Torpedo Level

Because of their tapered ends and short, compact designs, torpedo levels work best in situations where space is minimal. To use, you’ll:

1. Place on a level surface;
2. See if the bubble rests between both of the vial’s markings;
3. If not, adjust the level accordingly;
4. Repeat as needed.

Best Digital Level

How to Use a Digital Level

Except for its LED readout, using a digital level is similar to using a traditional model and can work in as many scenarios by doing the following:

1. Place your digital level on a flat surface.
2. Wait a few seconds for the level to calibrate.
3. Adjust as needed until the readout displays 0 degrees.
4. Check the readout against the vialed bubbles.
5. Recalibrate or repeat as necessary.

Best Bubble or Spirit Level 

Empire’s E90 Series Magnum Mason Level is 48” long and features two True Blue vials accurate to within .0005”, along with a durable aluminum reinforced frame. What’s more, its polycarbonate lenses resist fogging, and their vials are replaceable in case of damage.

• High-impact ABS plastic resists denting and won’t mar finished surfaces;
• Built-in measuring scale;
• Top-view window;
• Highly competitive pricing.

Cons:

• You won’t get all the bells and whistles at this price point.

How to Read a Bubble or Spirit Level

Are you looking for simple instructions about how to use a bubble or spirit level? Read through these four steps:

• Place the level on the surface you want to measure.
• Check that the vial’s bubble is spaced evenly between the two middle markers.
• If necessary, adjust the surface until it’s level.
• Repeat the process.

The Best Levels by Length

We mentioned it earlier, but it’s important to reemphasize that longer levels are more accurate than shorter models. This is because the greater area you can measure, the greater detail you’ll have regarding whether or not a surface is level.

Here’s a way to imagine it: Picture two levels resting on a 6′ two-by-four; one is 10″ long, and the other is 48″ long. Because the 48″ version spans a greater distance, you can check the two-by-four’s accuracy more accurately than a shorter model.

However, keep in mind that longer levels are also more cumbersome and less inclined to work well in cramped quarters than shorter versions. Therefore, we’d recommend purchasing the longest level you can use across the most jobs.

Best 8ft (96”) Level
