Single-Sided Or Double-Sided? Start With The Aisle
Use the finished footprint and selling faces to choose the right shelf position.Quick Buyer Answer
Single-sided shelves use the perimeter; double-sided gondolas use the center of the store. The choice changes aisle width, facings, base footprint, end treatment, and the number of frames in the order.
Use the guide below as a conversation starter with your supplier. You do not need a perfect specification before asking for help; the important thing is to make the open decisions visible and compare like with like.
Decision Snapshot
Compare the finished footprint and selling faces, not only the shelf catalog name. CZD's 4-post reference lists 365 mm single-sided width and 700 mm double-sided width, but the aisle and planogram decide which is productive.
| Choice | Published reference | Planning question |
| Single-sided | 365 mm width reference | Does it fit the wall run and closure? |
| Double-sided | 700 mm width reference | Is the island and aisle wide enough? |
| Both | 900/1200 mm lengths; 5 levels; 70 kg | Does the exact load and span pass approval? |
What To Send For A Quote
- Wall and island lengths
- Finished aisle targets and cart flow
- Facings, product loads, end units, and levels
- Destination, finish, and future expansion plan
Single-sided and double-sided shelves solve different layout problems. A single-sided run puts the display against a wall or column; a double-sided gondola creates an island that shoppers can reach from both aisles. The decision affects facings, aisle width, base footprint, end treatment, and the number of frames you need to buy.
CZD's 4-post reference gives a useful physical comparison: 365 mm single-sided width, 700 mm double-sided width, 900/1200 mm lengths, five levels, and 70 kg capacity. These are product reference values; the correct selection still depends on your planogram, merchandise, and finished clearances.
Start With The Floor Plan
Choose single-sided shelving when one side of the run is a wall, column, service zone, or controlled back-of-house edge. Choose double-sided shelving when the row sits in the selling area and both sides can carry products. Mark the finished base and product projection on the plan, not only the upright centerline.
| Question | Single-sided | Double-sided |
| Shopping access | One selling face | Two selling faces |
| Typical position | Wall or perimeter | Island row |
| CZD width reference | 365 mm | 700 mm |
| Main trade-off | Less floor depth, fewer facings | More facings, wider island and aisle coordination |
Calculate Facings And Aisle Impact
A 1200 mm shelf length can provide more horizontal space than a 900 mm bay, but the right length depends on product facings, upright pitch, transport access, and the number of bays that fit the wall or island. For an island, calculate the width of both selling faces plus the base and product projection before approving the aisle.
Keep shopping carts, wheelchair access, replenishment, emergency routes, and queue formation in the calculation. A double-sided bay can improve display capacity while making a narrow aisle uncomfortable; a single-sided bay can preserve circulation while losing a second selling face.
Match The Shelf To The Merchandise
Use the same shelf family when both sides carry comparable dry-grocery loads, then customize depths, dividers, hooks, or end units for special categories. Put heavier products and cases on approved lower levels. Confirm whether the published 70 kg reference applies to your exact span, bracket, shelf depth, and load pattern; never transfer a model's number to a different configuration without confirmation.
Consider Finish And Expansion
Single and double-sided runs may share upright and bracket interfaces, but their base, back panel, end, and accessory quantities differ. Standardize the interface first, then choose white, gray, black, wood color, or a customized gloss/matt finish by zone. CZD can provide 3D layout, customized fittings, capacity, thickness, and color options while keeping the approved component family visible in the BOM.
Make The Choice On A Zone Drawing
Send wall lengths, island lengths, aisle targets, product categories, facings, load, and the locations of columns, refrigeration, doors, and checkout. CZD can return a zone recommendation with single/double bay counts, end-unit needs, related product references, and a quotation direction rather than forcing one shelf type across the entire store.
Next Step For Your Project
Use single-sided shelving for controlled perimeter display and double-sided shelving for productive island rows. The right answer comes from the finished layout and merchandise plan; CZD Shelves can model both options and show the capacity, footprint, and component differences before you order.
