What Is a Good 40-Yard Dash Time?

A good 40-yard dash time depends heavily on the player’s position, but as a general rule anything around 4.5 seconds is considered fast for an NFL prospect, elite skill-position players run in the 4.3s, and the fastest times ever clocked at the NFL Scouting Combine sit around 4.2 seconds. There is no single “good” number, because a time that is elite for a 320-pound lineman would be slow for a wide receiver.

The 40-yard dash is the headline event of the NFL Combine, the most talked-about number in the whole pre-draft process. Here is what counts as a good time, broken down by position, and why context is everything.

What the 40-yard dash measures

The 40 is a straight-line sprint from a stationary three-point stance, timed electronically. It is meant to gauge a player’s explosive acceleration and top-end speed, traits that matter enormously for chasing down a ball-carrier or getting open deep, and far less for, say, a quarterback standing in the pocket.

That is the crucial framing: the 40 measures one physical trait, not football ability. Plenty of great players ran unremarkable 40s, and plenty of fast runners never made it in the league.

Good 40 times by position

Because heavier players cannot accelerate the same 40-yard distance as lighter, sprint-built ones, scouts read the number relative to position. Here is a practical guide to what “good” looks like across the roster.

Position	Elite	Good	Notes
Wide receiver / Cornerback	Under 4.40	4.40 – 4.50	Pure speed positions; deep threats want sub-4.4
Running back	4.40 – 4.45	4.45 – 4.55	Blend of speed and power
Safety	4.40 – 4.50	4.50 – 4.60	Range and closing speed matter
Linebacker	4.50 – 4.60	4.60 – 4.75	Bigger frame; sideline-to-sideline speed
Tight end	4.55 – 4.65	4.65 – 4.80	Fast for their size is a big plus
Quarterback	4.60 – 4.80	4.80 – 5.00	Rarely a priority for pocket passers
Offensive / Defensive line	Under 4.90	4.90 – 5.20	Anything sub-5.0 is impressive at their weight

Use these as guideposts rather than hard cut-offs. A cornerback running 4.38 turns heads; an offensive tackle running 4.95 turns heads just as much, for the opposite reason.

The elite tier: sub-4.3

Times under 4.3 seconds are extraordinarily rare and belong to a tiny group of the fastest athletes on earth. The all-time Combine record sits around 4.2 seconds, and only a handful of players in history have officially broken 4.3. When a receiver or corner posts a time like that, it can meaningfully raise their draft stock overnight, because game-breaking speed is so valuable and so hard to find.

For a sense of just how fast that is, consider that world-class 100-metre sprinter Usain Bolt is estimated, from his race splits, to have run around 4.2 seconds for 40 yards, and NFL burner Tyreek Hill has been timed in the low-4.2s to 4.29 range in unofficial settings. That is the ceiling of human straight-line speed.

When a slow 40 doesn’t matter

The counterpoint is just as important. Tom Brady ran a 5.28-second 40 at the 2000 Combine, one of the slowest quarterback times on record, and went on to arguably the greatest career in NFL history. For a pocket passer, the 40 is close to irrelevant; decision-making, accuracy and pocket presence decide everything.

The same logic applies to interior linemen, whose jobs are about power and technique in a phone-booth-sized space, not sprinting. This is why smart evaluators treat the 40 as one data point among many, height, weight, agility drills, tape and interviews all feed the final judgment.

How the 40 fits the bigger scouting picture

A blazing 40 can boost a prospect’s draft position and, ultimately, their earning power, since speed at premium positions is scarce and expensive. The players who translate that speed into production, piling up yards and touchdowns, are the ones who eventually command top contracts and tools like the franchise tag. If you want to see what elite athleticism looks like once it reaches the field, our look at the most rushing yards in a season shows speed turned into results.

It is also worth remembering the 40 is a very different test from endurance running; a great sprint time has little to do with, say, a good 5K time, which measures a completely different energy system. Explosive speed and stamina are separate gifts.

The bottom line

There is no universal “good” 40-yard dash time; the right benchmark depends on position. Sub-4.4 is elite for receivers and corners, mid-4.5s is solid for running backs, the 4.6s–4.7s range is good for linebackers and tight ends, and anything under 5.0 is strong for linemen. The very fastest ever hover around 4.2 seconds. And as Tom Brady proved, a slow 40 need not define a career, because the dash measures speed, not football greatness.
