Domestic house spiders possess elongated bodies with a somewhat flattened cephalothorax and straight abdomen. Their body/legs ratio is typically 50–60%, which accounts for a body size of 7.5–11.5 mm (0.30–0.45 in) in females and 6–9 mm (0.24–0.35 in) in males.[2]

Males are usually distinguished from females by having longer, more agile legs, bloated pedipalps and elongated abdomen. Other distinctions are strictly behavioral.

The coloring of an adult T. domestica is typically dark orange to brown or beige (maybe even grayish), with a common characteristic of striped legs and two dull, black, longitudinal stripes on the cephalothorax. The abdomen is mottled in brown, beige, and grey and has a pattern of chevrons running lengthwise across the top (similar to an argyle pattern).
