How to calculate minimum Aisle WidthsFor busy warehouse managers, choosing the right forklift is essential. It goes beyond lifting capacity and tire type, though. You have to consider your physical workspace to keep things optimized. Calculating your minimum aisle width will let you choose the right warehouse forklifts - but how do you figure out how much space you need for safe forklift operation?

What Is A Forklift’s Minimum Aisle Width?

A forklift’s minimum aisle width tells you how much space you need to safely navigate with a full pallet load. This minimum may still mean tight navigation, but with the right equipment and training, your operators will be able to navigate warehouse aisles safely and effectively. Depending on your priorities, you may build in more moving space to your warehouse for increased safety and convenience. 

How Do I Calculate Minimum Aisle Width?

Determining your forklift’s minimum aisle width is a fairly simple calculation:

  1. Enter your forklift’s Basic Right Angle Stacking Width, sometimes referred to as Right Angle Stack. 
  2. Add your load length
  3. Add 12 inches for clearance 

This total length is the minimum width needed for operators to safely maneuver with pallet loads. When calculating, you should use your largest pallet load length to ensure flexibility throughout your warehouse. You should calculate this figure whenever handling new or irregular pallet loads to make sure it is safe to do so. You should also check your minimum aisle width when considering new forklifts for your fleet to make sure they can be used in your workspace.
