Use broad categories
Baking, breakfast, canned foods and snacks are easier than dozens of tiny subcategories.
Design for turnover
Frequently replenished categories need predictable homes.
Avoid hidden duplicates
Deep shelves benefit from risers or pull-forward bins.
Keep important package information
Do not decant products when doing so loses preparation, ingredient, allergy or date information you still need.
Practical boundary. Measure first, respect product load limits, and do not improvise wall, ceiling or overhead installations when the structure or appropriate hardware is uncertain.
