These are some guidelines for a good retail design when you are setting up your shelving. You should place the best selling products and the products that have the best profit margins at eye level.
Sometimes companies will give you special deals on products if you place them in a certain location. You should also line up your products largest to smallest left to right, when there is more than one size of a product. This is because people naturally look from left to right.
By placing your larger products on the left you are more possible to have customers take the larger size, which makes you more sales. Empty space should be minimized as it uses up valuable space in your store and does not look good.
The space between shelves should just be a little more than is required for hands to take the product of the shelves. You should always ensure that your shelves are well stocked as this creates an impression of abundance and you will also lose sales if your shelves are empty.
