Deep Hive Body Dimensions

Last Updated on September 17, 2021

When it comes to beekeeping, getting your deep hive body dimensions right is critical to getting a Langstroth hive to work properly. Bee space is the foundation upon which trouble-free beekeeping is built. If you get your Langstroth hive constructed to the right beehive dimensions, your beekeeping will be largely trouble-free and fun. Incorrect deep hive body dimensions, or any part of the hive that is not built with bee space in mind, invites a world of irritation and pain into your life. In this article, we take a closer look at bee box dimensions.

Bee Space

When you first look at a beehive, it looks simple. It is basically a box with some frames in it, a lid, and a bottom board. Then you look at the price of a properly made beehive and you fall over backward. How can that little box cost that much?

A beehive is a piece of precision agricultural equipment. The box is built around the principle of bee space. If you get a measurement wrong, it will work less well.

Bee space is defined as a specific space dimension that bees will not build comb in. Quite simply, this is the distance between the surface of two combs in a hive. The space measures about 5/16th of an inch (8mm). Depending on the race or breed of bee this may vary a bit.

From the perspective of a bee, if she cannot get into a space to police it or clean it, that space could harbor pests. She will seal the space off to limit risk. If she can crawl into the space and police it, but the space is too small to build combs she will leave it open. Large spaces will be filled with comb.

How We Use Bee Space In A Deep Brood Box and Other Parts Of The Hive

Every part of the hive must employ bee space in its design. This means that a Langstroth hive will be built around a standard set of dimensions. Frames need to employ bee space. The distance between the frames and the side of the box needs to employ bee space and even the distance between the bottom of the frames and the next box needs to employ bee space.

A Langstroth Like Box – A Disaster

When I started keeping bees, I just found an old beehive box and then using a jigsaw and some old floorboards, a chisel, and a hammer, I built ten beehives. These were the worst beehives I have ever seen. They were horrible to use, and they taught me a lot of important lessons.

Lesson One – Do Not Use Second-Hand Wood

Floorboards recovered from old buildings have no service book that comes with them explaining what has happened in their lives. You do not know if they were treated with arsenic (popular up to the 1950s), painted PCP type wood preservative (popular until the 1980s), or have lead paint on them (popular up until the 1990s).

Buy virgin untreated wood if you are going to make your own hives.

Lesson Two – Cumulative Error

I took bad measurements off a hive that had been to hell and back. This was a beaten-up old beehive that had been around since the 1930s. It was actually made by AI Roodt company. So it was an excellent hive – but even a 60-year-old Rolls Royce gets tired.

Every time we make something, small errors creep in. If we then take measurements off the thing we have made, and use those to make the next thing, eventually, we get an accumulation of measurement errors and the results can be a significant deviation from the correct dimensions.

Never measure off a beehive and use those measurements to make a box. Always use a cutting list that is new, and correct. There are many excellent cutting lists out there such as this one and if you have a simple workshop – this one.

Lesson Three – What Happens When You Get The Dimensions Wrong

I got my first deep hive body dimensions wrong on 10 beehives. When you make a mistake like this, the bees glue the whole hive together – you cannot get the frames out without breaking the frames. Then honey pours all over the bees. This results in robbing and chaos.

Eventually, after two years of these cursed hives, I actually bought new, properly dimensioned hives, and then I took a crowbar, broke the old hives open and removed the frames, and transferred them to the new hives. It was a huge amount of work, and the time, lost production, and irritation dwarfed the money I “saved” by making my own bad hives.

Lesson Four – Do It Once, Do It Right

I have now learnt that if I am making hive parts, I aim to do it once, and do it right. I am 45 now – if I do this, the beehive parts I make now will see me through to when I am unable to work bees anymore. If I follow in the footsteps of one of my bee mentors, Mr. Hadley Timm, that means until I am 90. Although he has not stopped. Bees put a spring in the step of person.

Recommendations For Your First Hives

Buy Boxes

I would strongly recommend that your first hives are bought boxes. If you plan to make your own, rather use bought, high-quality hives. Learn how they work, and then based on this experience make your own.

Be very wary when buying old second-hand boxes – take an accurate measure – I actually use a digital caliper to measure the bee space gaps and a steel ruler. Check the measurements against a drawing of a hive.

I have had the case where I bought a set of hives from a guy. He made all his own hives and his bee space was perfect for his hives, but they were his own design. His frames were even his own size. Then we got these all mixed into the rest of our operation and for years they caused problems until we managed to get rid of the lot of the equipment.

We hope this article has helped you understand the absolute importance of metrology and sticking to the exact dimensions of a Standard Langstroth hive in your beekeeping. Please share, and learn from all my stupid mistakes, so you don’t make those. Make your own new stupid mistakes instead! That is progress.
