Shop Radiators by Size

We all know no two homes are created equal, and one of the biggest challenges this brings up is knowing what size of radiator a room needs. Trade Radiators has decades of experience in helping customers up and down the UK find the right sized radiator for every scenario; from studio apartments with only one spot for a radiator to open office floors that need heat all day long.

To help you find the right size your space, shop our range of models that go from 300mm tall to 1800mm wide.

What Factors Determine Which Size of Radiator to get?

When trying to get the right sized radiator, some factors you need to consider include:

• The space you have
• Your current heating system
• How easy/hard it is to eat the room
• Where the radiator is going to be located

A little research can go a long way to avoiding any radiator headaches from making a bad purchase. If you have any specific questions relating to the size of a radiator you’ve seen on our site, please get in touch directly with the team today, and we’ll be happy to help you find the perfect radiator.

What Sizes do Radiators Come in?

The most common radiator sizes in the UK are:

• 400mm x 400 mm
• 300mm x 1000mm
• 400mm x 1200mm
• 600mm x 1200mm
• 600mm x 900mm

What Should I be Looking for When Picking a Radiator Size?

It is important to know what heat output is required from both the radiator and the room it is going in. You don’t want to buy a new designer radiator and find out it doesn’t have the right BTU for the space.

To help you know what radiator you should get, we have a handy heating calculator here on the site. You enter the dimensions of the room and what type of space it is, and we’ll give you a clear idea of the BTU you need. That will then help you know whether a radiator is suitable or not.

What Size Radiator do I get for a Room with No Central Heating?

For anyone who has converted their attic to a new bedroom or carved out a special workspace in the office, you’ll often find that these smaller spaces don’t have piping for the existing system. When that’s the case, you’ll want to look at getting an electrical radiator. They come in the same makes and sizes but have a filling inside that helps you plug in and have the radiator on when you need it. You can find out more at our electric heating section.
