Zenius blocks are based on a mathematically-coordinated size methodology so they interact in a way that makes them logical and easy-to-use in small or large quantities. They are based on increments of 1.25” units. To illustrate, every cube of 1.25” x 1.25” will have a hole to line up with from one block to the next.
Large Beams: 1.25” x 10”
Medium Beam: 1.25” x 5”
Small Beams:1.25” x 2.5”
Large Block: 2.5” x 5”
Square Block: 2.5” x 2.5”
