All-Medium Hive vs Deep Brood Boxes: Which Setup Should You Choose?

The "classic" Langstroth setup uses two deep boxes for the brood nest and medium or shallow boxes above for honey. A growing number of hobbyists skip the deeps entirely and run every box as a medium.

Both setups keep bees perfectly well. The choice is about you: how much you can lift, how much you want to spend, how you plan to get bees, and whether you want every frame in the apiary to fit every box. If you are planning a spring equipment order, this is the decision to make first, because it affects every box and frame you buy afterward.

The box sizes, briefly

Langstroth boxes come in three common depths. Exact dimensions can vary slightly between manufacturers, but the commonly listed heights are:

Each box depth takes its own frame size. A deep frame will not fit in a medium box, and a medium frame in a deep box leaves a gap underneath that bees will fill with irregular comb.

Weight: the main reason people go all-medium

The math is simple. A deep box is about 9 5/8 inches tall, a medium about 6 5/8 inches. That means a deep holds roughly 45 percent more comb volume than a medium of the same width. When both are full of honey, the deep is heavier by about that proportion.

We are not going to give you a single weight for a full box, because it varies with how full the frames are, how much is honey versus brood, and whether you run 8-frame or 10-frame equipment. But anyone who has lifted a deep full of honey will tell you it is a different experience from lifting a medium.

If lifting is your main concern, the lightest combination is 8-frame mediums. Our 8-frame vs 10-frame guide covers the width side of that decision, and our beekeeping with a bad back guide covers other ways to reduce strain.

Interchangeability: one frame size for everything

The quiet superpower of an all-medium apiary is that every frame fits every box. That means:

• You can move a frame of brood into a honey super area, or a frame of honey down to a light brood nest.
• You can feed a struggling colony with a frame of honey from a strong one.
• Your nuc boxes, frames, foundation and spare boxes are all one size.
• Making splits is simpler because any frame can go anywhere.
• You stock only one size of frame and foundation.

With deep brood boxes and medium supers, you have two frame sizes to keep track of, and frames do not move freely between the brood nest and the supers. Many beekeepers manage this fine, but it is a real difference.

Brood space: three mediums vs two deeps

Two deeps give about 19 1/4 inches of box height for the brood nest. Three mediums give about 19 7/8 inches. The total space for brood and stores is broadly similar, which is why many all-medium beekeepers use three mediums where others use two deeps.

The trade-off is that the brood nest is split across more boxes with more gaps between them. Some beekeepers think a deep frame suits a large, continuous brood nest better, others see no meaningful difference. What we can say is that both setups are used successfully by many beekeepers. How much space a colony needs for winter depends on your region, so ask a local beekeeping club or extension office what is typical where you live.

Getting bees: the nuc problem

This is the most practical downside of all-medium. Many nucs are sold on deep frames. If you buy a deep nuc and run all mediums, those deep frames will not fit.

Options if you want all-medium:

1. Buy a package instead. Packages do not come with frames, so any box size works. Our packages vs nucs vs swarms guide compares the options.
2. Look for a supplier who sells medium nucs. Some do. Ask early, because they can sell out.
3. Start with a deep box at the bottom and transition. Install the deep nuc frames in a deep box and add mediums above. Over time, as the queen moves up, you can remove the deep frames when they are free of brood. This takes planning and patience.
4. Catch a swarm. Swarms can go into any box.

If you plan to buy nucs for years, deep brood boxes may simply be easier.

Inspections and frame count

Three 10-frame mediums hold 30 frames. Two 10-frame deeps hold 20 frames. That means more frames to pull and inspect in an all-medium brood nest, and more box breaks to lift and separate.

On the other hand, each medium frame is lighter and easier to hold steady, which some beekeepers find makes inspections more comfortable, especially for spotting eggs. Finding the queen can take longer with more frames. Our guide on how to find the queen helps either way.

Cost

An all-medium setup usually means buying more boxes and more frames for the same total space. Medium boxes and frames may each cost less than deeps, but you need more of them. Check current prices from your supplier for a full setup in each configuration and compare totals, including frames and foundation, rather than comparing box prices alone.

Shop hive lifts and lifting aids

If you stay with deeps but worry about weight, lifting aids can help. Our guide to hive lifts and carts covers the options.

What a starter order looks like in each setup

To make the comparison concrete, here is what one 10-frame hive might need in each configuration. The number of honey supers depends on your local nectar flows and colony strength, so ask a local beekeeping club or extension office how many supers beekeepers near you typically use.

Notice that the all-medium column needs more frames for the brood nest but only one frame size overall. Many beekeepers find that simplicity worth the extra frames. Others prefer fewer, bigger frames in the brood nest and are happy to keep two sizes on the shelf.

A hybrid option

Some beekeepers run one deep at the bottom and mediums above it. It reduces the heaviest lifting to a single box that rarely needs to come off, while keeping compatibility with deep nucs. The downside is that you still stock two frame sizes, and the deep frames cannot move up into the honey supers. It is a reasonable compromise if you are transitioning or buying deep nucs.
