The recommended construction for a top-bar hive body requires specific interior measurements to ensure structural integrity and ease of management. The interior bottom must be 10 inches wide, and the interior vertical height should be 12 inches. Crucially, the sides must slope outward at an angle of exactly 120 degrees relative to the bottom board, utilizing lumber that is at least 3/4 inch thick.
The success of a top-bar hive depends on the 120-degree side angle to prevent wall attachment and a maximum depth of 12 inches to ensure natural comb does not collapse under its own weight.
Critical Construction Dimensions
The Necessity of the Slope
The defining feature of a top-bar hive is the trapezoidal shape of the body. The angle between the bottom board and the sloping sides must be 120 degrees.
This specific angle is not arbitrary; it mimics the natural geometry bees prefer. By maintaining this slope, you discourage the bees from attaching their comb to the side walls (often called "burr comb").
Maximum Interior Depth
The interior height of the hive body should be 12 inches. While you may see variations in length, the depth is a critical limit.
In a top-bar hive, the comb hangs freely from the wooden bar without the support of wires or four-sided frames used in conventional hives. If the hive is deeper than 12 inches, the comb becomes too heavy when filled with honey.
Material Requirements
To maintain these dimensions and provide adequate insulation, the wood used for the body should be a minimum of 3/4 inch thick.
The front and back pieces of the hive must be cut as trapezoids to accommodate the 10-inch bottom and the outward-sloping sides.
Understanding the Trade-offs
The Risk of Increased Depth
It is a common pitfall to increase the depth of the hive in an attempt to gain more honey storage per bar. You must avoid exceeding the 12-inch limit.
Because natural beeswax comb is soft, a comb deeper than 12 inches is highly susceptible to structural failure. The weight of stored honey can cause the comb to detach from the top bar and collapse to the bottom of the hive, destroying the colony's work.
Precision vs. Approximation
While the length of the hive (how many bars it holds) is customizable, the cross-section dimensions are not. Deviating from the 120-degree angle or the 10-inch bottom width alters the bee space.
If the angle is too steep, bees will attach comb to the walls, forcing you to cut it free during every inspection. This agitates the bees and makes management difficult.
Making the Right Choice for Your Goal
Building a top-bar hive requires balancing specific biological constraints with your construction capabilities.
- If your primary focus is low-maintenance management: Adhere strictly to the 120-degree side angle to ensure combs remain movable and unattached to the hive walls.
- If your primary focus is comb stability: Ensure your interior depth never exceeds 12 inches, preventing the heartbreaking collapse of heavy honey combs.
Precision in these foundational dimensions is the single most important factor in creating a sustainable, manageable habitat for your bees.
Summary Table:
| Dimension Component | Recommended Measurement | Primary Purpose |
|---|---|---|
| Interior Bottom Width | 10 Inches | Foundation for trapezoidal structure |
| Interior Vertical Height | 12 Inches (Maximum) | Prevents comb collapse from honey weight |
| Side Wall Angle | 120 Degrees | Discourages bees from attaching comb to walls |
| Material Thickness | 3/4 Inch (Minimum) | Ensures structural integrity and insulation |
| Side Slope Type | Trapezoidal | Mimics natural geometry and improves management |
