Will it fit?
Enter your gear's dimensions to see which of our hard cases it fits. Each case is test-packed in 3D with your foam padding, and the closest fits are listed first.
Under the hood
How it packs
Enter your sizes and select Find cases. A 3D packing engine tests your gear in every case we stock, rotating and stacking it the way a careful packer would.
Step 01
Any way up
Enter length, width and height in any order. Each item is tried in every valid orientation, so a 30 × 10 × 5 lens fits a 32 × 12 × 6 case no matter how you entered it. Your foam padding is kept on every side.
Step 02
Largest items first
With more than one item, the biggest goes down first. Each following item tries every open position and rotation, and takes the one that keeps the load smallest, so a pedal sits on top of the duffel rather than beside it. Because no single packing order is always best, we run it a few times (biggest first, longest first, widest first, grouped copies first) and keep the tightest result.
Step 03
Each case packed separately
Each case is packed to suit its own shape, instead of one arrangement being reused for all of them. The same gear lies flat in a shallow case and stacks in a deep one. Cases that hold everything are ranked closest fit first, so the top result wastes the least space. Select a result's photo to view its arrangement in 3D.
Packing techniques. Beyond placing boxes in corners, the engine:
- Keeps several options open. Rather than committing to one arrangement, it carries the most promising few forward together, so an early placement that pays off later isn't discarded.
- Fills the gaps. A later piece can drop into the space between two already-placed items, as well as beside or on top of them. Space that would otherwise be empty gets used.
- Bridges a span. A piece can rest across two items below when their tops are level, touching, and fully cover its underside. That is stable in practice, so it is allowed. Overhangs and air gaps still are not.
- Spacing between items. Set a gap between items and each piece is packed inside a margin of that thickness. Neighbours touch the margin, never the gear, so the gap is preserved.
Optional item controls. Left at their defaults, every item rotates freely. Use them when gear must stay a certain way up, or when a set should travel together:
- Quantity. Enter 3 in Qty to pack three copies without retyping them. They pack as separate pieces and share one colour in the 3D view.
- Orientation. Choose Any, Upright or Flat. Upright keeps the item's height vertical (it can still turn on the spot). Flat rests it on its largest face and never stands it up.
- Group. Available when quantity is above 1. Packs the copies side by side as one block whenever they fit that way, even if a looser arrangement would be slightly tighter. It never rules out a case: if the copies can't stay together, they split into as few groups as possible.
Loading rules. A fit only counts if a person could load it that way: square to the walls, flat, right way up. These are not allowed:
- No tilting. Items sit square, at 90° angles only. No diagonal rods or leaning panels.
- No gaps underneath. Everything rests fully on the floor or on the items below it. No plank across a hollow.
- No overhangs. Nothing balances past the edge below it, so stacks can't topple.
- No tipped stacks. A stack is built by gravity and stays that way. It never flips onto its side to squeeze in.
Everything errs the same safe way. The tool may report doesn't fit when forcing it might work, but when it reports fits, your gear goes in. At worst you are pointed one size up, never one size short.
For the curious: perfect 3D packing is provably hard, so no tool can promise the perfect arrangement every time. This one packs the way a careful person does, large items first and small items in the gaps, and checks every placement.
