I had to take over this task recently. There was a birthday party and there was short of space.

On this occasion a 3 circuit labyrinth fits best. Nevertheless, it is good to have enough width for the path to walk. And a bigger middle. Thus I adopted a circular labyrinth with the path sequence 0-3-2-1-4.

A 3 circuit Knidos labyrinth

I had a space of about 4 m. As path width I chose 50 cm, the middle had a diameter of 1 m, and the overall diameter was 4 m. Thus arose a length of about 39 m for the walls which can be marked, e.g., very well with a rope. I have done this with two ropes of 20 m length.

But I was not really pleased with it. Since the middle seemed to me a little bit too small. I still hold the 4-fold path width as a good measure for the center.

Hence, I have developed a sort of prototype which I would like to introduce here:

A 3 circuit Knidos labyrinth with a dimension between axes of 1 m

The dimension between axes is 1 m, the center has 4 m and the overall diameter is 10 m. The walls have a length of 86.83 m, the way into the center amounts to 66.34 m. The other dimensions and the radii can be taken from the drawing.

One can split the whole distance of the walls: So I get 38.56 m from A to C, and 48.27 m from B to C (total length 86.83 m). This can be laid, e.g., with two ropes of 50 m and 40 m length.

The walls do not overlap and are made from one line, differently to the 7 circuit classical labyrinth.

Here you may see, copy or print the design drawing as a PDF file.

The whole is scaleable. That means that if you wish other widths or diameters, the radii, lengths (short all dimensions) will change accordingly. If, e.g., only a 4 m overall diameter is possible, the dimension between axes would become 40 cm and the internal radius 0.80 m (the center therefore 1.60 m). I must multiply all dimensions by the factor 0.4. The path length would be 26.54 m and the (splitted) walls 15.42 m and 19.31 m.

Here the dimensions of the prototype are multiplied by the factor 0.5. Everything becomes half as big: The dimension between axes 50 cm, the center 2 m and the overall diameter 5 m. The path length decreases to 33.17 m and the /splitted) walls are 19.28 m and 24.13 m (43.42 m added together).
