How to Size a Bin Box

Key Takeaways

  • Size a bin box from the shelving, not from the part. Length should match the usable shelf depth, width should divide the shelf run with no waste, and height should clear the shelf pitch with room to lift the box out.
  • Common industrial shelf depths are 12, 18 and 24 in, with shelf widths commonly 36 and 48 in. Those are widely used industry figures, not iBox stock sizes. Measure your own racking before ordering.
  • A bin box is an open front or open top container, so the front cut height is part of the spec. Too high and pickers cannot see the stock, too low and small parts fall out.
  • Minimum order is 100 boxes, from about $0.48 per unit at bulk volumes, confirmed on your written quote.

Bin boxes are the open fronted corrugated containers that live on shelving in a stockroom or on a pick line. Every other box on this site is sized around its contents. A bin box is sized around the shelf, and the contents come second. Get that order wrong and you end up with boxes that overhang, wobble or waste a third of every shelf.

Take three measurements off the racking

  1. Usable shelf depth. Front edge to whatever stops the box at the back, which may be a rail or a wall rather than the shelf edge. This becomes the bin box length, less about half an inch so it does not hang over the front lip.
  2. Clear shelf run. The usable width between uprights. Divide this by your intended bin width and see what remains. A run of 46 in clear takes seven bins at 6.5 in with a small gap, or five at 9 in with a wasted column.
  3. Shelf pitch. Vertical distance between shelves. The bin height has to be low enough that a picker can get their hand over the top and lift the box out, which in practice means a couple of inches of clearance above the box.

Then check the part fits

Only now do you look at the contents. Take the largest part that goes in the bin, at its widest, and confirm it fits the length and width you just derived. If it does not, you have a choice: change the bin layout so the run divides differently, or lay the part in a different orientation. Do not solve it by making one bin oversize, because a mixed bin size on the same shelf costs you the benefit of a tidy grid.

Front cut height

The defining feature of a bin box is that the front is cut down so stock can be seen and reached. That cut is a real spec decision:

ContentsFront cutReason
Small fasteners and loose partsHigh front, shallow openingStops parts spilling when the bin is pulled
Medium items picked by handAround half the bin heightVisible stock, still contained
Bagged or boxed itemsLow front or full open topFast grab, nothing to spill
Anything counted on the shelfLow front with a label panelCount without lifting the bin

Board, stacking and labels

Bin boxes get handled constantly, so board grade matters more than it does for a box that ships once. Single wall is usually fine for light parts on a supported shelf. Double wall is worth it where bins are stacked on each other, where parts are heavy, or where the bin is pulled and pushed all day. Ask for the board grade and the maximum gross weight to be written on your quote rather than described in adjectives.

Leave a flat, unprinted or lightly printed panel on the front face for labels. A bin that has to be relabelled every cycle count is a bin that will end up with tape over the print. Plain corrugated bins are also covered on our corrugated boxes page, which is where to order.

Ordering, minimum and turnaround

Minimum order is 100 boxes, from about $0.48 per unit at bulk volumes, confirmed on your written quote. The die is included, so a bin cut to divide your exact shelf run costs no more to tool than a near standard size. That is the strongest argument for going custom on a bin box: the value is entirely in fitting your racking.

Turnaround comes in three lanes: rush (expedited production with air freight), standard (air) and cost saver (sea), from about 7 business days plus 2 to 5 for delivery, with specialty imported items up to about 12 weeks. Rush adds about 7 to 25% depending on the job. We produce in West Chicago and in Guangzhou. If you want to work from the contents rather than the shelf, see what size bin box do I need.

Measure one shelf bay, count how many bins you want across it, and request a quote with those numbers. We will work the width back so the row fills the run cleanly.
