The Pace is a unit of length based on the distance covered by a human step. Its definition is highly variable and depends heavily on context, often referring to either a single step or a double step.

• Single Step Pace: Often informally estimated as the distance from the heel of one foot to the heel of the next foot in a normal walking stride. Common estimations range from 2.5 to 3 feet (ft) or approximately 0.75 to 0.9 meters (m). This is sometimes simply called a 'step' or 'stride'.
• Double Step Pace (Roman Pace): Historically, the most significant definition was the Roman passus, which measured the distance from the heel of one foot to the point where the same foot touches the ground again (i.e., two steps). This was standardized as 5 Roman feet, roughly 1.48 meters or 4.86 feet.

Due to its inherent variability and dependence on individual gait and terrain, the pace is not a standardized unit for precise measurement.

The pace is one of the most ancient and intuitive units of length, used across numerous cultures due to its direct link to human locomotion.

• Ancient Rome: The Romans formalized the passus (double step) as 5 pedes (Roman feet). This unit was fundamental to their system, with 1000 passus forming the Roman mile (mille passus), which heavily influenced the definition of the mile in later systems.
• Military Usage: Throughout history, armies used paces (both single and double) for marching cadence, estimating distances, and measuring fortifications or camp layouts. Standardized step lengths were often drilled.
• Informal Measurement: Before widespread standardized rulers and tapes, pacing was a common way for individuals to estimate lengths and distances for land, construction, or travel.

The pace gradually fell out of official use with the rise of standardized systems like the Imperial system (feet, yards) and the Metric system (meters), which offered greater precision and consistency.

While obsolete for official measurements, the pace still finds some use:

• Rough Estimation: Used informally to get a quick approximation of distances, such as the length of a room, a garden plot, or walking distances in hiking or orienteering.
• Military & Marching Bands: Concepts related to pace length and cadence remain relevant in drilling and formation marching.
• Historical Context: Understanding the pace (especially the Roman passus) is crucial for interpreting historical texts, military accounts, and measurements related to ancient structures or distances.
• Exercise & Fitness: Step counters (pedometers) measure activity in terms of steps, which are essentially single paces.
