A wolf spider typically weighs between about 0.1 and 1.5 grams, depending on the species, age, and sex.
Weight by size category
- Small wolf spiders: ~0.1–0.3 g
- Medium wolf spiders: ~0.3–0.8 g
- Large species (e.g., Carolina wolf spider): up to 1–1.5 g
What affects their weight
- Species (there are 2,000+ species worldwide)
- Sex (females are heavier, especially when carrying eggs)
- Feeding state (recent meals increase weight)
- Life stage (juveniles weigh much less)
For perspective, even the largest wolf spiders weigh less than a paperclip (~1 g).
