Shelf space doesn’t come cheap. And when you’re managing hundreds or thousands of products across a retail estate, deciding what goes where can start to feel like a very complicated game of Tetris. That’s where planograms come in. A planogram is a visual plan showing how products should be arranged within a retail space. It can map out everything from product positioning and number of facings to shelf allocation and promotional space. For retailers and brands, a good planogram can help make better use of limited space, improve product visibility, support category performance, and give store teams a clear layout to work from. Of course, creating the plan is only half the job. It also needs to work in the real world, where stock arrives late, promotions change, and someone inevitably puts the biscuits in the wrong place. In this guide, we’ll look at what a planogram is, why it matters, and some practical tips for using planograms to maximise your retail merchandising strategy. A planogram is a visual representation of how products should be positioned within a retail space. It shows where products should go and how much space they should be given. Depending on the retailer and category, it could cover a single shelf, a whole bay, a promotional display, or an entire section of a store. A planogram might specify: For retailers with multiple stores, planograms also provide a consistent reference point for implementation. That doesn't necessarily mean every store needs to look identical. Different store formats and customer profiles may require different layouts. The point is to make those differences deliberate rather than accidental. Retailers have a finite amount of space to work with. The question is how to make that space work as hard as possible. A planogram gives retailers a framework for making those decisions. Sales data might show that one product has a particularly high rate of sale, for example. Giving it more facings could help improve availability and reduce the amount of time customers are greeted by an empty shelf. Meanwhile, a slower-moving product may not need quite as much real estate. It’s not simply a case of giving your best seller half the shelf and calling it a day, though. Product profitability, customer behaviour, promotional activity, new product launches, and the role each product plays within the category all need to be considered. Planograms help retailers decide how limited shelf space should be allocated. Using sales and category data can highlight where additional space could make the biggest difference, while reducing the amount given to products that don't need it. Where a product sits matters. Its position, number of facings and the products around it can all affect how easily customers notice it. This is particularly important for new products. If you're launching something into an established category, hoping customers spot it among the usual suspects isn't much of a strategy. Different teams may interpret merchandising instructions differently, while stores may make local changes based on stock or available space. A planogram gives everyone a clear reference point. That can make it easier to implement changes consistently across a store estate. Planograms help retailers think about the category as a whole rather than treating every product as an island. Products can be grouped according to how customers shop, whether that's by brand, product type, price point, or size. The result should be a category that's easy to navigate while supporting wider commercial objectives. A planogram shouldn't be created based on gut feeling alone. There's plenty of useful data that can inform how products are positioned and how much space they receive. This might include: Historical sales data is an obvious starting point, but it's important to understand the story behind the numbers. A product that appears to have low demand may actually have spent several weeks out of stock. A product that had an unusually strong month may have benefited from a major promotion. Simply copying last year's sales figures into a planogram and calling it data-led probably isn't going to cut it. This is where retail data and analytics can help. The better your understanding of what's happening at product, category, and store level, the more informed your decisions can be. Look at sales and rate-of-sale data to understand which products are moving quickly, which are underperforming and where availability could be an issue. But don't stop at the headline numbers. A slow seller might genuinely have low demand. Or it might be tucked away somewhere customers rarely look. Context matters. A planogram shouldn't just answer "where does this product go?" It should answer "how does this entire category work?" Think about how customers browse and compare products. Which items naturally sit together? Does the layout make sense? The best structure will vary by category, but the principle is simple: make it easy to shop while supporting your commercial objectives. If a product is selling quickly, it needs enough space to keep up. Giving a high-volume product too little shelf space could mean frequent gaps and additional replenishment work. At the other end of the scale, giving a slow-moving product too much space could tie up valuable real estate. New products, seasonal lines and promotions may all justify a different approach, so there's no one-size-fits-all formula. Your standard planogram isn’t necessarily going to work during a major promotion. A discount, seasonal campaign, or new product launch can significantly change demand and the amount of space a product needs. Build upcoming activity into your planning rather than trying to squeeze it into the existing layout at the last minute. A planogram can look fantastic on a screen, but that doesn’t necessarily mean it will translate to the store. Make sure your planogram accounts for real product dimensions, fixture limitations, replenishment requirements, and the practical realities of implementation. A plan that's impossible to execute isn't particularly useful. Don’t assume a planogram has worked just because it has been implemented. Look at the results. Has category performance changed? Has availability improved? Are stores maintaining the layout? Comparing performance before and after a change can help you understand what's working and what needs another look. This is the bit that’s easy to overlook. You can spend plenty of time analysing data and creating the perfect layout. But if the planogram isn't implemented accurately, none of that work matters very much. That’s why your retail merchandising strategy is such an important part of the process. Store teams need clear instructions and practical support. Retailers also need visibility of what's actually happening in store so they can identify gaps between the planned layout and what's on the shelf.
