Forklift Aisle Width Calculator: Stacking aisle width from real forklift datasheets

Hi Product Hunt! I run ForkliftCompare, a spec database built from manufacturer data sheets. The problem: every forklift datasheet quotes an aisle width, but only for one standard pallet and a fixed 200 mm clearance. Change the pallet, turn it the other way, or add the extra 100 mm the British Industrial Truck Association recommends, and the published number no longer fits your racking plan. This calculator takes the truck's own published VDI 2198 dimensions (turning radius, load distance, internal turning radius) and your load, and applies the same formula manufacturers use: Ast = Wa + x + l6 + a. Every input shows where it came from, and the result is only offered for models whose maker publishes those figures, which today means 40 Hyster, Yale and Linde trucks. If you write about warehouse layout, there is a free embed code on the page, so you can put the calculator in your own article. I'd love feedback, especially from anyone who plans racking for a living: what would you want it to handle next (narrow-aisle trucks, reach trucks, other pallet sizes)?
