Understanding the volume and type of items helped me determine the size and configuration of the cabinet I required.

2. Choosing the Right Size

Size was a crucial factor for me. I measured the available space in my garage and made sure to consider the height, width, and depth of the cabinet. I found that tall cabinets are great for maximizing vertical space, while wider cabinets provide more surface area for larger items. I opted for a mid-sized cabinet that fit perfectly in my garage without overwhelming the space.
