Radiators by Size

Shop radiators by size and find the perfect fit for every space in your home. Whether you’re working with a compact room or a larger, open-plan area, choosing the right radiator size is key to achieving efficient heating and a balanced look. Our collection makes it easy to narrow down your options, helping you select a radiator that suits both your layout and heat requirements.

For rooms where wall space is limited, tall radiators offer a practical and stylish solution. Designed to make the most of vertical space, they provide excellent heat output without taking up too much width — ideal for hallways, kitchens or smaller living areas. Tall radiators can also double as a design feature, adding height and visual interest to your room.

If you’re heating a more compact space, small radiators are a great choice. Perfect for cloakrooms, en-suites or tight corners, these space-saving options deliver effective warmth without overwhelming the room. Despite their smaller size, many models are designed to provide efficient heat output, making them both practical and versatile.

Across the range, you’ll find radiators in a variety of styles, including vertical and horizontal designs, as well as options suitable for central heating systems and electric setups. With different widths, heights and heat outputs available, it’s easy to tailor your choice to suit each individual space.

Browsing radiators by size helps simplify your search, ensuring you find a heating solution that fits seamlessly into your home. Explore the full collection to discover radiators that combine the right proportions with reliable performance — keeping every room comfortable, whatever its size.
