Quick Scoop: How tall is Dec?

If by “Dec” you mean Declan Donnelly from Ant & Dec, his widely reported height is around 1.68 metres (about 5 feet 6 inches). That puts him slightly below the average height for a UK man, which is part of why his height often gets turned into a running joke on TV.

Why people keep asking

• Entertainment sites and tabloids repeat the same figure: 1.68 m / 5 ft 6 in.

• Fans notice the height difference when he stands next to Ant McPartlin (about 5 ft 8–9 in) or Holly Willoughby (around 1.70 m).

• His height has been teased on shows like I’m a Celebrity…Get Me Out of Here! and has even led to jokey edits of his online bios.

One small twist

Some outlets list him as 5 ft 5 in when converting from 1.68 m, but others round to 5 ft 6 in. In practice, both refer to essentially the same height, just rounded differently.

TL;DR: Declan Donnelly (Dec from Ant & Dec) is about 1.68 m tall – roughly 5 ft 6 in.
