I just received VEVOR's largest plyo box, with stencils on three sides saying 20x24x30 inches. It is actually 20x24x28 inches in size (minus a small fraction on each). LOL.Honestly, 28 inches on the long side is better for me, but it's absurd to stencil 30 on that side.I'm gonna saw the 24" sides in half and use two half-open 20x28x12 boxes as weightlifting organizers/stackers for my squats and deadlifts, with some pieces of stall mat and some stackers based on 2x4's or 2x6's. It'll be fun for me to try to build something that suits me.Marc
