Are these radiators odd/special sized?

Hi everybody.

I am currently renovating my house and it has come to the time to plaster the lounge. Therefore, I new to remove the old radiators that are in there. They are single skin radiators and look very old. Therefore, I want to replace them. So, I measured them both and promptly went onto google (and typed in standard radiator sizes UK) to source new radiators. However, I can't seem to find replacements at these sizes. Am I doing something wrong?

Radiator 1 (Very long, under a low bay window) 2390w x 450h
Radiator 2 1260 x 600

Your doing nothing wrong your old rads will be imperial measurements new ones metric.
Smaller one quite easy 1200 rad + 2 - 30mm extensions.
Larger one you would probably have to use a 2400 rad. Stelrad do them fairly sure Kartel do them as well

Myson still make imperial radiators, sized in mm, but it's probably cheaper to alter the pipework and buy a metric rad.

Thanks for the advice guys. Makes sense now. Now...to confuse things further please allow me to ask...Why are some brands a lot more expensive than others? I presume they are made from the same materials? Also, now I am changing from single skin Rads to double skin do I have to configure them differently because reading up on Google it makes me think I now have to take things like BTU's into account??? I just want to swap these 2 single skin radiators in the lounge for 2 double skin radiators. Can I do this without any problems?

If your existing rads are plain single rads
You will increase output if you use single type k1 / type11 rads if you go for double rads type k2 / type 22 you more than double output and can become dependent on having sufficient pipework size.
As for cost Finish is a bit better on some but in essence look a length of warranty.
