Zed's Ult is suppose to be 625, currently the range is 550. Proof in link
we used 
who has a 525 range: https://gyazo.com/44b9d7b9e864ad9d6833693828a1ce2a
here's zed's wiki on his Ult range: https://gyazo.com/ce4c78a563b1dbae397a6a1d93f37bc8
Nah, lets leave it. Zed is a pos anyways. [slayer-jinx-catface]
riot pls fix
525 attack range is equal to about 655 spell range, so TF's basic attacks should be outranging Death Mark by about 30 units (spell range measures between character centers while attack range measures between hitbox edges, so to convert attack range to spell range you need to add in both characters' hitbox radii, which for both Twisted Fate and Zed is 65 units each, for a total of +130). As someone else said, if you compared it to Annie Q then it would match up better.
Similarly, attack range indicators at max range will only need to line up with the target's hitbox edge, while spell range indicators at max range will need to line up with the target's center.
Comparing Auto Attack range with Ability range is actually not that accurate in most cases. This is because they're measured differently.
Auto attack range is measured from the outside of the character model. Ability range is measured from the center of the character model.
I would suggest testing this again, except use Annie as a point of reference. Her Q range is exactly 625 units, which is what Zed's ult should be. So if she can Q him notably before he ults, then yes, his ult range is in fact bugged.
If not, I can do it later after work and verify it myself.
