How to Design Modular Gondola Shelving for Various Store Sizes

Understanding Modular Gondola Shelving

Gondola shelving is a freestanding retail fixture composed of a flat base and a vertical panel. The vertical panel often features slots, notches, or pegboard, which support adjustable shelves, hooks, dividers, and other accessories. Unlike fixed four‑post shelving, gondolas offer adaptability, allowing shelves to be repositioned with ease.

Modular gondola systems take this a step further by making every component interchangeable. Uprights, shelves, and brackets are designed so that they can be added, removed, or reconfigured—giving retailers the freedom to build single-sided wall runs, double-sided aisle units, or standalone islands. This makes modular gondola shelving especially beneficial for businesses that expect to evolve their merchandising strategy over time.

Assessing Your Store Space & Layout Requirements

Measuring Floor and Vertical Space

Begin by measuring your sales floor’s square footage and vertical clearance. Taller gondola units enable you to leverage vertical merchandising—stacking products higher without expanding your floor footprint. For inspiration and modular system designs, you can explore RUMIS’s modular display system solutions on our Systems page.

Planning Customer Flow

Selecting the right layout is essential:

• Racetrack Layout: Encourages a continuous, circular path that brings customers past all product zones.

• Power Aisle Layout: Focuses on a central aisle, ideal for showcasing high-margin or impulse products.

• Island Layout: Uses freestanding gondolas to form product islands, promoting fluid traffic and exploration from all sides.

Choosing Between Single‑Sided and Double‑Sided Units

Single‑sided gondolas are perfect for wall runs, particularly in narrow or perimeter‑focused stores. In contrast, double‑sided gondolas excel in central aisles of medium- to large-sized stores—they offer twice the display space per footprint, making them efficient for maximizing merchandise exposure.

Selecting the Right Gondola Components

Dimensions: Height, Width & Depth

Selecting appropriate dimensions ensures that your shelving fits the store layout efficiently while maximizing display potential. It also allows for a balance between accessibility and product visibility across different store sizes.

• Height: Options commonly range from 48″ up to 96″, letting you exploit vertical space for more merchandise. Taller units enable layered product presentation, allowing you to stock more items without crowding the floor or reducing aisle space.

• Width: Standard bay sizes, such as 36″, 42″, or 48″, accommodate most retail needs, but custom widths are available for unique layouts. This flexibility ensures that each gondola can adapt to varying product types and store aisle configurations.

• Depth: Shelf depths vary depending on inventory, with typical options from about 10″ to 24″ to suit compact or bulkier items. Selecting the correct depth ensures that products are easy to reach while maintaining a tidy and organized appearance on the shelves.

Material and Finish

Select resilient materials such as cold-rolled steel for strength and durability. Steel construction provides long-term stability under heavy loads, while maintaining a professional and clean look that complements any retail environment.

Powder-coated finishes not only look clean and modern but also protect surfaces from scuffing, corrosion, and daily wear and tear. This ensures the shelves maintain their aesthetic quality and functionality over time, even in high-traffic stores.

Back Panels

Use back panels like pegboard, slatwall, or mesh to support accessories. These panels provide versatile mounting options for hooks, shelves, or bins, allowing the retailer to customize displays according to changing merchandise or seasonal promotions. 

Back panels enhance merchandising flexibility by providing secure attachment points for accessories, while also allowing for easy reconfiguration of product placement without needing to rebuild the entire shelving system.

Accessories & Customization

Modular gondola systems support a wide variety of accessories:

• Dividers: Keep similar items grouped and shelves orderly.

• Hooks/Pegs: Ideal for hanging small or packaged goods.

• Baskets/Wire Bins: Perfect for bulkier or irregularly shaped merchandise.

• End Caps/Signage: Turn end-cap modules into eye-catching, promotional or thematic focal points.

Special Configurations

• Angled or Tilted Shelves: Improve visibility by presenting products at a slant, ideal for books, flat items, or promotional goods. Angled shelves enhance the shopper’s line of sight and make browsing more intuitive, encouraging impulse purchases. 

  4‑Way / Island Shelves: Offer 360° product access—maximize floor space by presenting items on all sides of the unit. These configurations are ideal for creating central store islands, increasing customer engagement, and promoting cross-merchandising opportunities across multiple product categories.

Designing for Different Store Types

Small/Boutique Stores

In smaller stores, favor lower-height gondolas to preserve sightlines and make the space feel more open, creating a comfortable shopping environment. Combine wall-mounted units with a few small double-sided islands to increase display options while maintaining open aisles. Modularity allows you to change configurations seasonally without replacing the whole system, offering flexibility for new product displays or seasonal promotions.

Medium-Sized Stores (Pharmacies, Specialty Shops)

Use double-sided gondola aisles supplemented by island units to create logical shopping zones, guiding customers through different product categories. Dedicate end caps to high-margin or seasonal items, attracting attention to key promotions and maximizing sales potential. Leverage modularity to reconfigure shelves quickly for promotional cycles or inventory shifts, maintaining a fresh and appealing store layout throughout the year.

Large Supermarkets / Big‑Box Retailers

In larger environments, tall gondola units help exploit vertical space, efficiently displaying more products without increasing floor footprint. Long runs of double-sided shelving maximize product exposure, creating organized aisles that accommodate high-traffic areas. Custom end-cap modules highlight seasonal or high-margin categories effectively, boosting promotional visibility.

Merchandising Strategy: Effective Use of Gondola Shelving

Flexibility & Future Proofing

Reconfiguration Capabilities

Modular shelving can be reconfigured quickly: reposition shelves and accessories, add or remove units, or rework layouts easily to keep up with trends, promotions, or changing merchandising needs. This is exactly the kind of adaptability RUMIS promotes in our modular display system guide, helping retailers future-proof their store design.

Scalability for Growth

Begin with a modest setup and expand as your business grows. Modular systems let you scale by adding units, changing panel types, or increasing height—without scrapping existing fixtures.

Sustainability & Longevity

Modular gondolas are built for reuse: you can refurbish, reconfigure, or repurpose parts instead of discarding. This reduces waste, lowers long-term costs, and supports more sustainable retail operations.

Installation & Operational Considerations

Assembly Best Practices

Start on a level base and ensure all base plates are perfectly aligned to maintain stability. Insert uprights securely and snap in shelf brackets carefully. Connect starter and add-on units to build long, continuous aisles.

Safety & Visibility

Balance shelf height with store sightlines so units do not obstruct customer views or create safety hazards. Ensure that each unit is stable and secure, adhering strictly to load ratings specified by the shelving provider to prevent tipping, overloading, or accidents. Proper placement also enhances customer comfort and navigational flow, contributing to a safer shopping environment.

Maintenance & Upkeep

Regularly inspect brackets, uprights, and hardware for looseness, wear, or damage to ensure stability. Use dividers and organizational tools to keep shelves orderly, simplifying restocking and inventory management. Routine cleaning and upkeep maintain a professional appearance while extending the life of modular shelving components, reducing long-term operational costs.

Common Mistakes & Best Practices

• Avoid Overcrowding

  Cramming products onto shelves reduces visual appeal and can overwhelm shoppers. Leave sufficient space between items to create a clean, accessible display that encourages browsing and improves the overall shopping experience.

  Maximize Vertical Space

  Neglecting vertical space wastes valuable merchandising real estate. Use taller shelving units where possible to display more products efficiently, enhancing product visibility while keeping aisles open and organized.

  Use Accessories Strategically

  Hooks, baskets, and dividers are essential merchandising tools, not afterthoughts. Use them strategically to organize products, improve accessibility, and increase the flexibility and functionality of each shelving unit.

  Invest in Good Signage

  Clear, prominent signage and well-designed end-cap graphics guide customers through the store and highlight promotions. Effective visual communication drives attention, encourages purchases, and enhances the overall shopping experience.

  Maintain Regularly

  Loose brackets or shifting shelves compromise both safety and aesthetics. Regular inspections and maintenance preserve structural integrity, functionality, and appearance, ensuring a safe, attractive, and reliable retail environment for customers.

Conclusion

Designing modular gondola shelving across different store sizes requires a balance of layout planning, thoughtful component selection, merchandising strategy, and operational flexibility. By leveraging modular systems—adjustable shelves, durable materials, and scalable configurations—retailers can create attractive, efficient, and future-ready displays that adapt as their business evolves.
