Correct size of radiator for BTU calculations

[Glasgowman]

Hi I’ve done a BTU room calculator, going by the calculations I need a radiator 6407 BTU, and 1877 watts. I’ve found a radiator just over these calculations at 6581 but in the description delta T65 is 6581. Delta T50 is 4695. Delta T30 is 2433. I have a recently fitted combi boiler. Would this radiator be fine for my room? Or do I need the T50 readings to be the same as my room calculation? Thanks for any help 👍🏻

Needs to be dt34 or dt29

So dt50 size would be 10.5k btu

So would the one above not be sufficient for my room?

If I calculate my room at 6407, what reading of radiator should I be looking to buy?

I’m pretty confused as tried a few different calculators and they’ve all gave me totally different readings ranging from 3000 to 6000. Thanks

Should I be looking for a rad with (delta t50 10.5btu readings) even though the calculator says I need 6407btu? Cheers
