What Is the Rule of Three?

The rule of three is an eCommerce visual merchandising principle in which three items are grouped together to create a more aesthetically pleasing and balanced composition. By using this technique, retailers can effectively enhance their visual displays and improve overall customer engagement.

People naturally find groups of three visually satisfying, making this arrangement an effective tool for creating engaging and memorable displays.

A classic example of the rule of three in visual merchandising is the mannequins in a clothing store window. Three mannequins are placed together and dressed in coordinating outfits. This creates a sense of unity and linkage amongst the products while also allowing each individual item to stand out and grab the customers' attention.

Benefits of the Rule of Three in Visual Merchandising

  • Creates effortless comparisons: Grouping products in sets of three gives shoppers an easy way to compare similar items, simplifying their purchasing decisions and encouraging exploration of product options.

  • Showcases product variety: By strategically arranging products according to the rule of three in visual merchandising displays, stores can offer a quick glimpse of the wider selection available, even if every item isn’t displayed.

  • Encourages display experimentation: Visual merchandising with the rule of three invites creativity, whether arranging mannequins side-by-side or stacking products in a pyramid shape, helping to capture attention and potentially increase sales through refreshed layouts.
  • Enhances cross-selling and upselling: The Rule of Three allows retailers to place complementary (cross-sell) and premium (upsell) products alongside the primary item, boosting the chance of additional or more profitable sales.

How to Use the Rule of Three to Your Advantage

Product Listings

Improve your product listings by implementing the rule of three in your product images, especially when your products come in a variety of styles, sizes, and colors. With a single image, you can give customers a quick overview of your product range, allowing them to easily visualize their options at a glance and encouraging them to explore further. This simple technique not only enhances the shopping experience but can also lead to increased engagement with your listings.

Example: Staghead Designs showcases the variety of a particular jewelry design in one image (different metal and gemstone types). By placing the items asymmetrically in a pyramid or triangle, customers are encouraged to consider all three products because their eyes constantly move between the jewelry pieces, and their attention remains on this core merchandising display.

Product Recommendations

Promoting products in small groups not only allows customers to make quick and easy comparisons but also creates valuable opportunities for upselling and cross-selling. By grouping related products that complement each other—rather than just variations of the same item—you encourage customers to consider additional purchases that enhance their original choice. This strategy can increase both customer satisfaction and sales, as shoppers are exposed to more options that might meet their needs or elevate their experience.

Example: Princess Polly implements the rule of three in their product recommendations. If a customer is looking for a prom dress, Princess Polly suggests three of their other items that will complement the dress and "complete the look". This visual merchandising technique doesn't overwhelm the customer and encourages them to stay on the website.

Additional Tips for Using the Rule of Three

  • Select related items: Choose three items that are closely related, even if they aren’t identical, to create a cohesive and appealing display.

  • Experiment with arrangements: Test different positions and arrangements, such as placing mannequins side-by-side instead of back-to-back, to see what catches shoppers’ attention.

  • Track sales impact: After setting up a new display, monitor sales to see if grouping products in threes has a positive effect. If successful, consider applying this strategy throughout the store.

  • Use lighting strategically: Highlight triplet displays with focused lighting to make them stand out and draw customers' attention.
