The Data
The 5.5 Inch Threshold, Explained by the Numbers
XLDating's endowed dating category opens at 5.5 inches erect - comfortably above the global average. Here's why that line, and not 6, 7 or 8, is the one we drew.
5.16″
Global average erect length across 15,000+ men
Veale et al., BJUI 2015 systematic review
14.47cm
Average stretched length, the Americas - largest globally
Mostafaei et al., 2024 WHO meta-analysis
6.4″
Length women report preferring for hookup partners
Prause et al., PLOS One study
Here's the thing: the British Journal of Urology International (BJUI) 2015 review, which pooled data from over 15,000 men, settled the question of "average" in a way porn never could. The mean erect length is 5.16 inches. The mean girth is 4.59 inches. Almost everything you've been told elsewhere is a marketing inflation or a locker-room lie.
Setting our threshold at 5.5 inches places verified XLDating endowed members above the global average without making the category artificially exclusive. It also aligns closely with the 6.4-inch preference women report for short-term partners (Prause), and the regional averages reported in Mostafaei's 2024 WHO meta-analysis, which placed the Americas highest at 14.47 cm stretched. We dive deeper into the math in our penis size statistics guide - but the short answer is this: 5.5 inches is honest, evidence-based, and meaningful to the admirers searching the platform.
