6 Best Bubble Levels for Beekeeping
Ensure straight, manageable comb by perfectly leveling your beehive. Discover our top 6 recommended bubble levels for this essential beekeeping task.
There’s nothing more frustrating than opening a hive for inspection only to find a tangled mess of cross-comb connecting five frames together. You can’t pull a single frame without destroying brood, spilling honey, and angering the entire colony. This common beekeeping headache almost always stems from one simple, overlooked detail: an unlevel hive.

Why a Level Hive is Crucial for Straight Comb
Bees build their comb with an uncanny sense of precision, using gravity as their guide. They construct perfectly vertical sheets of wax, leaving just the right amount of "bee space" between them for movement. When your hive is tilted, the bees don’t care. They still build straight down, following the pull of gravity.
The problem is, your frames are not hanging straight down; they are tilted with the hive box. This mismatch forces the bees to build comb that angles across the frames, welding them together. This is called cross-combing or burr comb, and it turns a simple inspection into a destructive, sticky mess. You risk "rolling" and killing your queen, you can’t properly check for pests or disease, and you make harvesting a nightmare.
A level hive isn’t just about aesthetics. It’s a foundational requirement for encouraging bees to build within the confines of the frames you provide. Getting this right from the start saves you countless hours of frustration and helps maintain a calm, manageable colony. The goal is a hive that is perfectly level from side-to-side, with a very slight tilt forward to help with drainage.
Bee Smart Hive Level: Designed for Beekeepers
If you appreciate a tool designed for a single, specific job, the Bee Smart Hive Level is for you. This isn’t a repurposed construction tool; it was created with the apiary in mind. It’s a small, L-shaped level that hangs neatly on the corner of a hive box, allowing you to check for level in two directions at once.
Its greatest strength is convenience. You can simply hang it on the top edge of your brood box and see both the side-to-side and front-to-back tilt simultaneously. Some beekeepers even leave them on their hives year-round for quick checks. This makes it incredibly easy to see if a hive has settled or been disturbed by weather or wildlife.
The tradeoff for this convenience is durability. Most are made of plastic and won’t stand up to the same abuse as a heavy-duty torpedo level you might have in your workshop. But for its intended purpose—quick, accurate hive leveling—it excels. It’s an excellent choice for new beekeepers who want a foolproof tool or anyone managing multiple hives who values speed.
Klein Tools 935AB4V: A Versatile Torpedo Level
Sometimes the best tool for the job is one you already own. A high-quality torpedo level like the Klein Tools 935AB4V is a versatile workhorse that’s perfect for leveling hives and a hundred other tasks around the farm. Its compact size makes it easy to toss in your bee kit, but it’s packed with features that are surprisingly useful in the apiary.
The standout feature for beekeepers is often the magnetic edge. If you use a metal hive stand, you can stick the level right to it, freeing up your hands to adjust shims. The built-in vials for level (horizontal), plumb (vertical), and 45-degree angles give you all the information you need. The bright, high-visibility vials are also easy to read in the dappled sunlight of a bee yard.
This type of level represents a smart investment. You’re not buying a "beekeeping level"; you’re buying a great all-around level that happens to be fantastic for beekeeping. It’s more durable than specialty plastic levels and its utility extends far beyond the apiary, which is a major plus for any hobby farmer trying to get the most out of their tool budget.
Swanson PL001M Post Level for Hive Stand Legs
Getting your hive level starts with the foundation. If your hive stand is wonky, you’ll be fighting an uphill battle forever. The Swanson Post Level is a specialized tool designed to ensure the legs of your hive stand are perfectly plumb, or vertically straight, from the very beginning.
This tool straps directly around a post, like a 4×4 or 2×4 leg, and has bubbles on two or three sides. This lets you see if the post is leaning forward, backward, or sideways all at once. By getting each leg of your stand perfectly plumb, you create a stable and true foundation, which makes the final step of leveling the hive platform itself incredibly simple.
While you can achieve the same result with a standard torpedo level, it’s a much slower process of checking one side, then the next, then re-checking the first. The post level is an efficiency tool. If you’re building several hive stands at once, it’s a massive time-saver that ensures a professional, consistent, and stable setup for your entire apiary.
Sun Company Lev-o-gage for 360-Degree Checks
For the beekeeper who appreciates constant data, the Sun Company Lev-o-gage offers a different approach. Originally designed for RVs and boats, this inclinometer gives you an at-a-glance reading of your hive’s tilt on two axes simultaneously. It’s a small, self-contained unit that you can mount directly onto the side of your hive.
Instead of a bubble, it uses a tube and ball system to show the degree of tilt both side-to-side and front-to-back. The primary benefit is continuous monitoring. In areas with soft ground or significant frost heave, a hive can settle over the seasons. A quick glance at the Lev-o-gage tells you immediately if an adjustment is needed, without ever having to get out a separate tool.
This isn’t the most precise tool for the initial setup; a traditional bubble level is better for getting it perfect the first time. But for long-term monitoring, it’s fantastic. It’s a "set it and forget it" solution for anyone who wants to be proactive about keeping their hives perfectly aligned year after year.
Empire EM81.9G: A Durable Magnetic Option
The Empire EM81.9G is the definition of a reliable, no-nonsense tool. Built with a heavy-duty extruded aluminum frame, this torpedo level is designed to withstand the drops, bumps, and general abuse that come with farm work. If you’re looking for one level to serve your apiary and workshop for years to come, this is a top contender.
Its powerful magnetic edge provides a secure grip on metal hive stands, while the top-read window is a game-changer. This feature allows you to look down on the level to read the bubble, rather than craning your neck to look at it from the side—a small detail that makes a big difference when you’re hunched over a hive. The high-contrast vials are easy to read in various lighting conditions.
Think of this as the rugged, all-purpose choice. It doesn’t have the bee-specific design of the Bee Smart level, but it more than makes up for it in sheer toughness and practical features. It’s the kind of tool you buy once and trust completely, making it a smart, long-term investment for any serious hobbyist.
Irwin Hanson String Level for Apiary Setups
Leveling a single hive is one thing; setting up an entire apiary with a long, straight row of hives is another. This is where a simple string level, like the one from Irwin Hanson, becomes indispensable. This tiny, lightweight level has hooks that allow it to hang from a tightly pulled mason’s line or string.
To use it, you drive two stakes into the ground at either end of your proposed hive row. You then stretch a string taut between them and hang the string level in the middle. By adjusting the height of the string on one of the stakes, you can create a perfectly level line spanning 10, 20, or even 50 feet.
This tool is for macro-level planning. It allows you to set all your hive stands at the same height, creating a clean, professional, and orderly apiary. It ensures that even on sloped ground, your row of hives looks uniform and is easier to work with. It’s not for the final, precise leveling of each individual hive, but it’s the absolute best tool for establishing the baseline for your entire bee yard.
How to Properly Level Your Hive, Step-by-Step
Getting your hive level is straightforward, but the details matter. Rushing this step will only create more work for you later. It all starts with a solid, stable foundation that won’t sink or wobble.
First, place your hive stand in its final location. Put the bottom board on the stand, then place your level on top of the bottom board, parallel to the entrance. This checks the side-to-side level. Use durable, rot-resistant shims like cedar shingles, flat stones, or scraps of pressure-treated wood under the legs of the stand until the bubble is perfectly centered. Don’t use materials that will compress or rot quickly.
Next, turn your level 90 degrees so it’s pointing from the front to the back of the hive. Here, you don’t want it to be perfectly level. You want a slight forward tilt, with the front of the hive just a little lower than the back. This is crucial for drainage, as it ensures any rain that blows into the entrance or condensation that forms inside will run out instead of pooling on the bottom board. Aim for the bubble to be about half-a-bubble’s width off-center, toward the back of the level.
Once your bottom board is set, the hard work is done. You can stack your hive boxes on top, and they will all follow the perfect foundation you’ve just established. Be sure to re-check your hives each spring, as the ground can shift and settle during the winter freeze-thaw cycle.
A good level is one of the most important, yet inexpensive, tools in a beekeeper’s arsenal. It’s not about making your apiary look pretty; it’s a direct investment in the health of your colony and the ease of your inspections. Take the ten minutes to get it right, and your bees will reward you with beautifully straight comb season after season.
