# Thread: YFull STR match distances

1. ## YFull STR match distances

Hello.
I don't know if this belongs here, I haven't found a YFull thread.
Can someone help me understand the STR - match distances on YFull ( Y dna )?
I have the following matches, the closest one shows a distance of 0.026. How would that translate into years (Closest common ancestor) or generations?
Thank you

4. ^ I have a 0.031 match at Yfull I've tried using the formula in the link ,i.e 0.031x 67/111 =GD, but I'm getting nonsensical results. Could someone please do it for me?

0.031 * 67 = 2.1

0.031 * 111 = 3.4

You match would be up to 3/67 and up to 4/111
