About 3/8ths of an inch.

Oftentimes, lightning bolts will appear thin to the naked eye, which is a result of light being diffracted as it moves through the cloud. This makes the bolt look narrower than it really is, which contributes to this commonly-held myth that they’re about three inches in width. In reality? They’re more like three eighths of an inch wide on average.
