Inputs
Formula Used
- Shelf height: (CabinetHeight − (Shelves−1)×ShelfThickness) / Shelves − Clearance
- Max items per stack (stacked): floor(ShelfHeight / (ItemHeight + StackGap))
- Max items per stack (nested): 1 + floor((ShelfHeight − ItemHeight) / (ItemHeight×NestingRatio + StackGap))
- Stacks needed: ceil(Quantity / MaxPerStack)
- Required shelf width: Σ(Stacks × SlotWidth), where SlotWidth ≈ Diameter + SideGap (or Thickness + DividerGap in vertical mode)
- Available shelf width: CabinetWidth × Shelves × UsableSpace%

Example Data Table
| Scenario | Cabinet (W×D×H) | Shelves | Inventory | Modes | Typical Outcome |
|---|---|---|---|---|---|
| Garden kitchen cabinet | 80×50×120 cm | 4 | 6 pots, 5 pans, 6 lids, 4 trays, 5 bowls | Pots/Bowls nested; Pans/Lids/Trays vertical | Fits with moderate usage; fewer unstacking steps |
| Compact shed cabinet | 60×40×90 cm | 3 | 4 pots, 4 pans, 4 lids, 2 trays, 3 bowls | Mostly stacked, minimal dividers | Tight fit; add dividers or reduce stack height |
| Wide pantry base | 100×55×90 cm | 2 | 8 pots, 8 pans, 8 lids, 6 trays, 6 bowls | Mixed vertical and nesting | Fits, but needs zones for weight distribution |
Measure and Map Usable Volume
Start with cabinet width, depth, and height, then record shelf count and thickness. The planner converts your units and estimates shelf height after subtracting shelf boards and a chosen clearance. Usable space percentage (often 70–90%) reserves room for fingers, liners, and airflow, which prevents wedging and reduces scratches.
Prioritize Access Frequency
Group cookware by how often you use it: daily pans at waist level, weekly stockpots higher, and seasonal canners or roasting trays lowest. The calculator’s mode selection helps you compare stack, nest, and vertical layouts, so you can minimize reach distance while keeping heavy items closer to the cabinet bottom. In garden kitchens, store dry items away from damp towels.
Select Safe Stacking Heights
Stacking works best when the shelf height supports stable piles. The tool estimates items per stack using shelf height divided by item height plus a stack gap. A small gap (0.2–0.5 in) allows easy lift-out. If you enable weight limits, keep each shelf under its rated load by splitting quantities across shelves. As a rule, place cast iron and Dutch ovens on the lowest shelf to reduce drop risk.
Use Zones and Dividers
Vertical dividers are ideal for baking sheets and cutting boards because they use thickness rather than height. The planner translates divider gap into “slot width,” then totals required width across shelves. Nesting reduces height consumption by applying a nesting ratio, which is useful for mixing bowls and measured sets. Reserve one “buffer slot” for future additions and for items that dry slowly after outdoor washing.
Maintain, Review, and Scale
After you calculate, review the overflow warnings and the recommended assignments by shelf. Adjust usable space, clearance, or divider gap to reflect real hardware, then rerun. When you buy new cookware, update quantities and dimensions; the same cabinet can stay organized if you refresh the plan quarterly. Use the CSV export to track inventory, and print the PDF view to tape inside the door as a quick guide.
FAQs
Q1. What if my cabinet has a face frame or hinges that reduce clearance?
Measure the narrowest usable opening, not the outer box. Reduce the usable space percentage or cabinet width to match hinge and frame intrusions, then recalculate to avoid false fit.
Q2. How do I choose a good usable space percentage?
Start at 80% for standard shelves. Use 70% if you add liners, pullouts, or bulky handles. Increase toward 90% only when shelves are open and access is unobstructed.
Q3. When should I use vertical dividers instead of stacking?
Choose dividers for flat items like sheets, griddles, and boards. If an item is awkward to lift from a stack or risks scratching, vertical slots reduce contact and improve retrieval.
Q4. How do I estimate nesting ratio for bowls or similar sets?
If bowls nest tightly, use 0.35–0.55. For looser nesting, use 0.60–0.80. Lower ratios save more height but require consistent shapes. Adjust after a test stack and rerun.
Q5. Why does the planner show overflow warnings even with extra depth?
Depth does not increase width-based capacity for stacks or divider slots. If required shelf width exceeds available width, reduce quantities per zone, enable nesting, add shelves, or allocate a second cabinet.
Q6. Can I use this planner for an outdoor kitchen or potting shed cabinet?
Yes. Keep usable space conservative, and separate cookware from wet tools. Allow more clearance for humidity and towel storage, and prioritize corrosion-resistant racks for frequently rinsed items.
