How Are Track Lanes Measured in Track & Field?
Summary
A standard outdoor track is 400 meters around — but have you ever wondered how that distance is actually measured? The secret is that each lane is measured 20 cm from the inside line. This consistent method ensures every athlete, whether in lane 1 or lane 8, runs the correct distance.

Track Lane Measurement Basics
| Feature | Measurement Standard |
|---|---|
| Lane Width | 1.22 m ± 0.01 m (4 ft) |
| Measurement Point | 20 cm from the inside line of the lane |
| Standard Track | 400 m measured in lane 1 |
| Additional Lanes | Each lane adds ~7–8 m per lap |
Why 20 cm From the Line?
Ensures fairness — athletes don’t benefit from running directly on the line.
Accounts for natural running paths (most athletes run slightly away from the edge).
Creates consistent lane-to-lane distance increases.
Lane Distance Differences
Every lane outside lane 1 adds distance because of the curve radius.
Lane 1: Exactly 400 m.
Lane 2: ~407 m.
Lane 3: ~414 m.
Lane 4: ~421 m.
Lane 8: ~453 m.
That’s why in staggered starts, outer lanes begin farther ahead.
The Role of Staggered Starts
Used in races with curves (200m, 400m, 4x100, 4x400).
Aligns each lane so the total distance run is equal.
Based on geometric calculations of the curve radius and the lane’s extra length.
Track Variations
Indoor Tracks: Typically 200 m with tighter curves and banked turns. Lane measurement is still 20 cm from the inside line.
Oversized Tracks: 300–400 m indoor tracks exist, changing stagger calculations.
Non-Standard Facilities: High school or older tracks may vary, but the 20 cm rule is the standard.
FAQs
Q1: Why not measure from the very inside edge?
Because no runner can place their foot exactly on the line the entire way — 20 cm accounts for natural running space.
Q2: Do staggered starts make outer lanes harder?
Yes and no. While the distance is equal, outer lanes feel harder because of reduced visibility of competitors.
Q3: Why do sprinters prefer middle lanes?
Balance of curve radius and visibility — lanes 3–6 are considered most favorable.
Q4: Are lane widths always identical?
Yes — World Athletics requires lanes to be uniform width (1.22 m) for fairness.
Key Takeaways (TL;DR)
Track lanes are measured 20 cm from the inside line.
Lane 1 = 400 m; each additional lane adds ~7–8 m per lap.
Staggered starts ensure fairness in races with curves.
Lane width is standardized at 1.22 m worldwide.
