Short answer: Most retail shelf dividers are 1/8 in. clear acrylic, as long as the shelf is deep and 4 to 8 in. tall, with a bent foot 1.5 to 2 in. wide that sits under the product so its weight holds the divider in place. Use 3/16 in. for dividers taller than about 8 in. or for heavy items like bottles and boxed goods.

What size and thickness to choose

Length is the shelf depth, minus about 1/2 in. so the divider doesn't stick past the front edge or hit the back wall. Height depends on what you're dividing: 3 to 4 in. for cosmetics, cards, and small packets; 6 in. for boxed goods and folded apparel; 8 to 10 in. for tall bottles and books.

  • 1/8 in.: the standard for dividers up to about 8 in. tall. Light, low-cost, and thin enough not to steal shelf space.
  • 3/16 in.: taller dividers, heavy products, or anywhere customers push items hard against the divider.
  • 1/4 in.: stockroom and warehouse bins, or dividers that stand without a foot in a slotted rail.

Ways to hold a divider in place

Bent foot (L divider)

The most common style: the bottom 1.5 to 2 in. is bent to 90° and slides under the products, so their weight keeps the divider upright. One piece, no hardware, and it moves anywhere on the shelf. We line-bend the foot after cutting; see acrylic bending.

T divider

A foot that extends to both sides holds products on the left and right, which is better for narrow facings.

Front-rail or clip-on

For shelves with a front rail or a channel strip, we cut a tab or notch along the bottom edge to fit it. Bring us the rail profile, or one sample divider that fits.

Slotted grid

Flat dividers with half-depth slots that interlock into a grid, the same way drawer dividers work. Good for bins, cubbies, and sorting trays.

How we make it

We laser-cut dividers from a single drawing, so a run of fifty is identical. The cut edges come out smooth and glossy, which matters on a shelf where hands brush the front edge all day. Then we bend the foot along a straight line. If you only need flat dividers that drop into slots, there's no bending step at all; price them as plain rectangles in the cut-to-size service.

Tip: round the top front corner with a 1/4 to 1/2 in. radius. It looks finished, stops shoppers snagging sleeves or bags, and is less likely to chip if a cart bumps the shelf.

Colors and finishes

Clear keeps products fully visible and works with any store design. A colored or white divider can mark categories or brands; an engraved or printed label on the front edge strip (bent or bonded at the front) doubles as a shelf talker. For a premium shelf, frosted dividers look softer and hide scuffs.

Design tips

  • Measure the shelf depth at several points; shelves with lips or price channels lose usable depth.
  • Make the foot no wider than the narrowest product, or it'll lift the product it's meant to hold.
  • Add a slot or notch at the front if a price strip runs along the shelf edge.
  • For displays that also lift products, see risers and display stands.

Questions

Will acrylic dividers work on glass shelves?

Yes. A bent-foot divider stays put under the product's weight. For extra grip, add small clear silicone bumpers under the foot.

Can I use them in a refrigerated case?

Yes. Acrylic handles refrigerator and freezer temperatures fine, though it's a little more brittle in the cold, so avoid snapping dividers into tight rails when they're frozen.

How many dividers can you make in one order?

From a handful to hundreds. They're cut from full sheets, so large runs are efficient and priced with quantity discounts.
