The largest online community devoted to celebrity height is located at Celebheights.com. It features more than 7500 celebrity-height pages and about 1000 photos of the celebrity standing next to a fan whose height has been verified.
CelebHeights features discussions between users in a comment section on each profile page. Some posts indicate whether the picture or the encounter occurred at night time. This can influence a height estimation, as the spine compresses slightly throughout the day. Users on CelebHeights gather data from social media accounts, newspaper articles, and other published media to make their judgements. Some heights are estimated based on photos of multiple celebrities standing near one another, when one celebrity height is known.
