How to Measure Radiator Covers (Irish Guide)
Measuring your radiator correctly is the most important step in choosing the right radiator cover. A well-fitted cover not only looks great, but also allows proper heat circulation and prevents the cover from blocking valves, skirting boards or pipework — all of which are common in Irish homes.
This powerofone.ie guide walks you through the exact steps to measure your radiator accurately, using simple tools and taking into account the typical features found in Irish houses.
What You Need Before You Start
All you need is a tape measure and a minute or two. It’s best to note your measurements in centimetres, as this is how most radiator cover sizes are listed.
1. How to Measure Radiator Width
Start by measuring the full width of your radiator. This must include the outer edges of the end caps and any valves on the sides. These parts often extend slightly beyond the main radiator body, so measuring only the panel will give you an incorrect size.
Once you have the width, add at least 5cm. This extra space allows the cover to slide over the radiator comfortably and ensures proper heat movement inside the cover.
Example:
If your radiator measures 100cm wide, look for a cover around 105–110cm wide.
2. How to Measure Radiator Height
Next, measure from the floor to the top of the radiator. In many Irish homes, older radiators have slightly taller brackets or pipes that sit above the main panel, so include anything that rises higher than the radiator itself.
After you get your measurement, add 3–5cm. This creates enough clearance so the cover doesn’t rub or sit directly on top of the radiator.
Example:
If the height is 82cm, a cover around 85–90cm tall works well.
3. How to Measure Radiator Depth
Depth is the distance from the wall to the furthest front point of the radiator. Be sure to measure the deepest point, including any fins, ridges or brackets that stick out.
Add an extra 2–4cm to this measurement. This ensures the cover doesn’t press against the radiator and allows warm air to circulate properly.
Example:
If the depth is 15cm, choose a cover 18–20cm deep.
4. Check Your Pipework and Valves
Many Irish radiators have pipes that come up from the floor rather than out of the wall. Check where your pipes are positioned and ensure they will not interfere with the legs of the radiator cover.
If your pipes are close to the radiator or sit directly below it, you may need a cover with:
-
an open-bottom design, or
-
cut-outs to accommodate pipework.
This is completely normal — nearly all Irish homes require this consideration.
5. Consider the Space Around the Radiator
Before choosing a size, make sure the cover will fit the surrounding area. Measure the distance to nearby door frames, skirting boards, furniture, or window sills. A few extra centimetres ensures the cover can slide into place easily without hitting anything.
6. Ventilation is Important
A good radiator cover should never trap heat. Make sure the style you choose includes a top grill or vent, along with slats or cut-outs on the front panel. Your added measurement clearances help promote airflow, so the radiator can still heat your room efficiently.
7. Standard Radiator Cover Sizes in Ireland
Although every home is different, most radiator covers fall into these common Irish size ranges:
-
Small: 78–90cm wide
-
Medium: 100–120cm wide
-
Large: 120–152cm wide
-
Extra-Large: 152–180cm wide
If your radiator sits between two sizes, it’s always better to size up so the cover sits comfortably around the unit.
