Best Overall Bubble Level

Stabila Type R 300 Series

If I had to pick just one bubble level line to work with, it would be the Type R 300 series from Stabila. I like the overall shape of their Type 196-2 series better along with its hand holds. However, the R shape of the 300 series is crazy-strong and more resistant to abuse over the long haul.

The trade-off is that there are only two measuring surfaces and three marking edges, unlike standard box levels that can measure and mark all the way around. That said, the learning curve isn’t very steep, so I don’t think it’s a big downside.

Key Decision Factors

• Type: Box level with a unique “R” shape
• Accuracy: 0.0004 inches per inch
• Available Sizes: 24, 32, 48, 72, and 96 inches

48-inch Price: $153

Best I-Beam Bubble Level

Sola HPL Series Bubble Levels

Comparing most I-beam levels usually boils down to the visibility and accuracy of the vial. However, Sola’s HPL series takes what’s typically an entry-level tool and makes real improvements. If you’re only concerned about the basics, the magnified FOCUS vials are easier to read and more accurate than most.

From there, Sola’s I-beam frame has a modified design with a triangular structure at the top and bottom that makes it more rigid than other I-beam levels. Doing that adds weight, but it’s still lighter than box beam levels using the same quality and thickness of aluminum.

If you’re shopping for an I-beam level in hopes of a lower price, this isn’t for you. The same goes if you’re looking for a wide range of lengths. These high-precision levels have a premium price point, and just two sizes are available covering the classic door jamb set.

Key Decision Factors

• Type: Modified I-beam
• Accuracy: 0.0003 inches per inch
• Available Sizes: 29.5, 71 inches

29.5-inch Price: $139.55

71-inch Price: $257.49

Best Box Bubble Level

Milwaukee Redstick Box Levels

There are only a handful of players in the premium box level class and my favorite is the Milwaukee Redstick level. You can’t see what sets it apart in durability—an all-metal backbone. Inside the frame, multiple ridges are running along the interior which gives it outstanding durability compared to other box levels. It’s not quite as strong as Stabila’s R 300 series, but it’s a significant advantage over most of Milwaukee’s competition.

The Sharpsite vials give the level excellent visibility compared to standard vials. There’s also no compromise in accuracy with a 0.0005 inches per inch rating.

Like its competitors in the premium class, the additional innovations also increase the price, though it’s not as high as Stabila. Fortunately, you can grab a case to protect your favorite bubble level. There are also multiple level sets in the Redstick line to help save some money if you need more than one size.

Key Decision Factors

• Type: Box level with internal reinforcement
• Accuracy: 0.0005 inches per inch
• Available Sizes: 16, 24, 32, 36, 48, 59, 72, 78, and 96 inches

48-inch Price: $99.97

Best Digital Level

Sola Big Red Digital

Deciding on the best digital level was one of the biggest challenges as I was evaluating the options. It’s a popular style for dealing with gradients, and there are several genuinely good choices.

Sola’s Big Red Digital Level nails the same accuracy digitally that its premium competitors do and takes advantage of its high-accuracy/high-visibility FOCUS vials for backup. The design also ensures it’s structurally durable and protected against the elements with an IP65 ingress rating.

The backlit digital readout has a host of functions and features, many that you can also find on other high-end digital levels. However, Sola sets itself apart with Bluetooth connectivity to its Measures app.

The trade-off is that it’s one of the most expensive models on the digital scene.

Pro Tip: When buying a digital level, get one with vials as a backup in case batteries die or the electronics get damaged.

Key Decision Factors

• Type: Digital box level
• Accuracy: 0.0003 inches per inch
• Digital Accuracy: 0.05° at 0° and 90°, 0.1° at other angles
• Available Sizes: 10, 24, 48, and 72 inches

48-inch Price: $314.65

Best Adjustable Expandable Bubble Level

Stabila Type 106T/TM Series

When you add moving parts to a level, maintaining accuracy is a huge challenge, so we look to the most reputable brands to deliver professional results. Still, even the best expandable level can’t maintain its top accuracy in the extended position.

This category came down to the Milwaukee RedStick expandable levels and Stabila’s Type 106 plate levels. Choosing between them was tough, and there’s still disagreement among our crew.

Milwaukee’s highlights over Stabila include high-visibility Sharpsite vials and more importantly, a no-maintenance build. Not having to do regular upkeep on your expandable levels makes working them more convenient. Milwaukee’s levels are also less expensive than Stabila’s.

Both levels are highly accurate in the retracted position. On paper, they equal each other in extended accuracy, as well, varying just ±0.15 inches over a 144-inch extended length. However, we noticed a little flex in Milwaukee’s level when it’s at its maximum extension.

One last point is that Stabila’s design is lighter; something that can make a difference when you’re positioning the level overhead.

In the end, maintaining accuracy across the full length of the extension is the key that puts Stabila in the win column, but it’s certainly not a decisive win.

Reasons to Buy

• Durable build
• Excellent retracted accuracy
• Higher extended accuracy than competitors
• Also available in magnetic versions

Consider Another Model if…

• You want a no-maintenance model
• You’re looking for a less expensive model
• You want higher visibility vials

Key Decision Factors

• Type: Expandable box level
• Retracted Accuracy: 0.0004 inches per inch
• Extended Accuracy: 0.001 inches per inch
• Available Sizes: 72 – 120 and 84 – 144 inches

72-inch Price: $365

84-inch Price: $398

Best Mason’s Bubble Level

Kapro 930 Smartcast

Mason’s levels have to be tougher than most. It’s not just the concrete surfaces they work on, it’s the way masons tap them to level brick and block during construction.

Several models stand out to me, and for a mason’s level that’s flat-out tough, I like the Kapro 930 SmartCast. It’s a cast aluminum non-standard I-beam style that gives you gradient measurements up to 2% and has rubber strike pads on each end.

It’s not just a strong level, though. Kapro uses its Optivision vials with highly visible red edges and it maintains the 0.0005 inches per inch accuracy we’re looking for. With Kapro offering its best vial technology in such a touch mason-focused build, it’s easy to recommend.

Key Decision Factors

• Type: Cast modified I-beam
• Accuracy: 0.0005 inches per inch
• Available Sizes: 16, 24, and 32 inches

24-inch Price: $49.99

Best Torpedo Bubble Level

Empire Level em75.10

There was once a time when choosing the best torpedo level wasn’t too challenging, but today, there are so many different varieties and job-specific options that it’s overwhelming. While there are several quality candidates to top the list, Empire Level’s em75.10 is the torpedo level I turn to most often.

It has the accuracy I demand, Empire’s easy-to-read True Blue vials, and a solid feature set. What seals the deal is that it has an affordable price tag that makes it an excellent value and it’s a Made in the USA product using global materials.

Key Decision Factors

• Type: Magnetic Torpedo
• Accuracy: 0.0005 inches per inch
• Available Sizes: 10 inches

Price: $18.97

Best Pocket Bubble Level

Kapro 946 Smarty

Like torpedo levels, you have a lot of options when it comes to pocket levels. Which one is the best for comes down to what features you need. Some Pros will undoubtedly want additional features such as Milwaukee’s 360° rotating vial or the digital readout on Sola’s digital pocket level. For the way I work, the Kapro 946 Smarty gets my vote. I don’t need a lot of bells and whistles for a pocket level and this one gives me everything I need while skipping what I don’t.

A single Optivision Red vial offers 0.0005 inches per inch accuracy with 1% and 2% gradient lines to quickly check horizontal installs with the high-vis red edges that make it easy to read. It’s locked into a reinforced 4-inch magnetic frame that carries easily in your pocket or tool bag.

Key Decision Factors

• Type: Pocket Level
• Accuracy: 0.0005 inches per inch
• Available Sizes: 4 inches

Price: ~ $10

Best Bubble Level Set

Stabila Type 80 AS-2 Bubble Level Set

When it comes to high value, nothing beats buying a set of levels to take advantage of combo pricing. For my money, the best set is Stabila’s Type 80 AS-2 set. The Type 80 series features Stabila’s high-accuracy vials set in an economical box design. It’s not a basic box level, though, and has reinforcing ribs running the length to improve the overall durability along with slip stoppers to reduce movement while you’re marking.

The set includes 48-inch, 24-inch, and 12-inch levels, covering the most common applications professional tradesmen encounter daily.

Key Decision Factors

• Type: Box level
• Accuracy: 0.0004 inches per inch
• Included Sizes: 12, 24, and 48 inches

Price: $139.16

Best Bubble Level for the Money

Empire Level e75 Series

I’ve used a lot of levels over the years and when I’m looking to get the most bang for my buck, I turn to Empire Level’s e75 series. They’re not the cheapest levels you can buy, and they’re not the most expensive, either.

Key Decision Factors

• Type: Box level
• Accuracy: 0.0005 inches per inch
• Available Sizes: 24, 48, 72, and 96 inches (plus a 32/78-inch jamb set)

48-inch Price: $49.89

Best Bubble Level Brands

There are several quality brands to choose from. Here are the ones we recommend most highly:

• Empire Level: Inventors of the torpedo level, Empire Level has an outstanding balance of visibility, accuracy, and price.
• Milwaukee: High visibility, excellent accuracy, and extreme durability define Milwaukee’s core Redstick level line.
• Stabila: The gold standard among professionals, Stabila has built its reputation on outstanding accuracy and high durability across an impressive range of level types.
• Sola: Excellent durability and accuracy with some of the highest visibility available on its magnified Sola Focus vials.
• Kapro: These Israeli-designed levels go for a reverse contrast vial that shows red edges and is easier to see than standard vials. Excellent durability and accuracy are built in as well.

Types of Bubble Levels

There are several spirit level types available. While this isn’t an exhaustive list, it’s a good overview of the styles our team uses most often.

• I-beam: Just like steel I-beams used in bridge construction, the “I” shape provides structural strength while remaining lightweight.
• Box: Heavier but stronger than I-beam levels, box levels use a box structure for its strength.
• Torpedo: Plumbers and electricians use these compact levels to check small sections. They often include additional markings to cover gradient requirements.
• Digital: Typically built into a box level design, digital levels offer an easy-to-read digital readout to verify your angle.
• Expanding: This type of level collapses for easier storage and transportation and is designed to expand to cover much longer distances than standard level types.
• Mason’s: Levels specifically designed for concrete use have to be built more durably because masons tend to hit them with a trowel or mallet to get bricks and blocks flush with one another.
• Pocket: The smallest of all levels, pocket levels usually feature just one vial and can sometimes rotate to identify specific angle targets. Their small size makes them useful in tight spaces and easy to carry in a tool box or tool belt.

Best Bubble Level Features to Look For

• Accuracy: A bubble level is only as good as its ability to give you a truly level measurement. We prefer to use levels with 0.0005 inches per inch accuracy or better. On a 48-inch level, that gives us a maximum error of +/- 0.024 inches, or 3/125 of an inch. However, less expensive and smaller levels like torpedo and pocket models often fall short of that mark.
• Visibility: The most accurate bubble level in the world doesn’t mean diddly if you can’t see the bubble. Different colors and high vial contrast help a lot.
• Durability: Bubble levels do most of their work on jobsites where the environment isn’t as forgiving as the living room where you’re trying to hang a picture. You’ll want to avoid plastic.

Optional Features

• Magnetic: Magnets are great for acting as a third hand when you’re working around steel.
• LED lights: Battery-powered lights really help the visibility of a spirit level when you’re working in low light or varying light conditions.
• Digital levels: Some Pros enjoy the convenience of a digital readout rather than just a vial, especially when you’re working toward specific grades like wheelchair ramps.

Why a Bubble Level?

Bubble levels have been around for a long time. Even though cross-line lasers are a more elegant option, the bubble level still trumps them in several areas. Lasers lose visibility as soon as you step into the light, limiting their usefulness outside. And while a laser can be more accurate, it’s better for longer distances than what you’ll use a spirit level for. There’s also the convenience factor – you usually go for your spirit level when you’re making frequent checks for level and plumb work. Cross-line lasers take more time to set up.

What is More Accurate than a Bubble Level?

Cross-line lasers can be more accurate than a bubble level. With an accuracy of ±1/8-inch or better, it exceeds the accuracy of most professional-grade bubble levels. Cross-line lasers are also better at covering long distances than bubble levels.

Is a Box Level or I-beam Level Better?

There’s a trade-off between box levels and I-beam levels. The boxy structure of a box level tends to be stronger while an I-beam level tends to be lighter. Both are appropriate for professional use.

What is the Level Bubble to the Right?

Many levels have three vials, and they can vary based on the type. Typically, the middle vial is for horizontal leveling. From there, some levels have two vials perpendicular to the middle one for vertical leveling using either side.

Some levels—usually torpedo levels—have one vertical vial and another set to 45° on the right. This is a common installation angle for some pipes and conduits.

Can a Bubble Level be Wrong?

A bubble level can be wrong, especially if there’s damage to the frame. You should check the accuracy of your level from time to time using a straightforward process.

• Set the level on a flat surface
• Note the position of the bubble (taking a picture on your phone for comparison can help)
• Flip the level 180° left to right (not up and down)
• Note the position of the bubble again

If the bubble is in the same spot on both checks, it’s accurate and you’re good to go. If the position shifts at all when you flip it around, it’s inaccurate and you shouldn’t trust it.

Why Are Stabila Levels So Good?

Stabila levels enjoy an outstanding reputation in the construction industry thanks to their precision build along with using materials and designs that have high durability. Their higher standard is reflected in their prices, so expect to pay more if you want the best.
