What is the difference between stride and step?

A step is from one foot to the next foot; a stride is from one foot back to the same foot, so it spans two steps. This tool uses stride, the standard full-cycle measurement, because it best distinguishes gaits.

How does track spacing reveal the gait?

Faster gaits stretch the prints apart. A walk has a short stride relative to body size; a trot lengthens it; a lope or bound clusters prints in groups with long gaps. The stride-to-track-length ratio separates these patterns.

Is this a definitive species identification?

No. Track size and stride overlap between species, and substrate distorts prints. Use this as a shortlist, then confirm with toe count, claw marks, heel pad shape, gait pattern, and habitat before deciding.

Why does straddle width matter?

Straddle reflects how wide the animal stands. Waddling animals like raccoons and bears show a wide straddle, while a direct-register canine trail is narrow. Combined with stride it helps separate similar-sized species.

Does substrate affect the measurements?

Strongly. Deep snow and mud lengthen and distort prints, while a bounding animal in snow may register a single compound impression. Measure several clean tracks and average them for a reliable reading.

Wildlife Track & Gait Spacing Reference

A trackway tells a story in its spacing. This reference takes the three core measurements trackers use — stride, straddle, and print size — and classifies the gait while shortlisting the mammals whose tracks fit your numbers.

How it works

Gait is inferred from the ratio of stride length to track length. Roughly:

ratio = stride / track length
walk:  ratio  up to ~5
trot:  ratio  ~5 to 9
lope:  ratio  ~9 to 14
bound: ratio  above ~14 (prints in tight groups, long gaps)

Species matching brackets your print length and stride against published reference ranges for common mammals (e.g. domestic dog, coyote, red fox, bobcat, raccoon, white-tailed deer, black bear). A species is listed when both your track size and stride fall inside, or near, its typical range.

Example and tips

A 2.5-inch print with a 16-inch stride and a 4-inch straddle gives a stride-to-track ratio near 6.4 — a trotting gait — and the size brackets coyote and a medium dog. Always measure several clean prints and average them, and confirm with toe count and claw marks: canines register four toes with claws, while felines like bobcat show four toes usually without claw marks.
