A stepped acrylic display riser fails in one of two ways: a shelf bows under the stock, or a joint goes white. Both are decided before the sheet is cut, and both show up in the first month of trading.
A menswear chain ordered 140 three-step risers for a spring rollout. Forty of them came back with delaminated joints, all from the same supplier and the same production week.
Acrylic display riser dimensions that work on a counter
- Step rise: 100 mm, 150 mm or 200 mm, the three common conventions
- Step depth: 250 mm for folded garments, 150 mm for cosmetics
- Width: 300 to 600 mm, in 100 mm increments to suit a bay
- Sheet: 4 mm clear for garments, 5 mm for bottles and jars
Depth is the number buyers get wrong. A 150 mm step looks right in a drawing and then cannot hold a folded shirt plus a size marker. Measure the stock, add 50 mm, and design the bay backwards from that.
Joints, bowing and the edge polish
Solvent welding gives the seamless look but leaves a line that has to be polished out. Where the joint will be seen edge-on, a two-part adhesive with a controlled bead is the better choice, provided the parts sit in a jig for 24 hours.
Bowing is a span problem. A 4 mm shelf at 500 mm deflects about 3 mm under 10 kg; at 300 mm the same shelf deflects 0.4 mm. Adding a 20 mm front lip turns the shelf into a beam and cuts deflection dramatically, which is cheaper than going up a gauge.
Edge polish is what separates a riser that reads as premium from one that reads as a workshop job. A diamond-polished edge is clear; a sanded edge is white and looks unfinished. On a retail floor under spotlights, the difference is obvious from two metres away.
When the risers sit in a lit bay, the light transmission of the acrylic matters as much as the thickness. Clear cast at 92 percent is standard; a tinted or frosted finish changes the read of the merchandise. The frosted acrylic sheet guide covers the diffusion options.
Where the riser sits on an existing counter, plan the footprint so the base does not overhang. Our acrylic display stand guide covers the counter-top formats that pair with stepped risers.

Frequently Asked Questions
What thickness acrylic for a display riser?
4 mm for steps up to 300 mm wide, 5 mm to 6 mm beyond that or when the shelf carries more than 5 kg. A 4 mm shelf at 500 mm span bows visibly under a stack of folded garments.
Do risers need a front lip?
A 5 mm to 8 mm lip is worth adding on any step that carries round or rolling stock. Without it, bottles and cosmetics migrate forward and end up on the floor.
How are clear acrylic risers joined?
Solvent welding for a seamless look, or two-part acrylic adhesive where joints must be invisible and the parts are thick. Bonded joints need 24 hours at temperature and must not be polished before cure.
