Same rule of thumb as Watch Finder: case diameter of about 23.5% of your wrist circumference (−2 mm to +2.5 mm), and lug-to-lug no longer than about 29% of it plus 1 mm. A guide, not a rule; flat or round wrists differ.
Strap fit
Both take 12 mm straps, so straps move between them. Size charts: Tissot lug width chart · Tissot lug width chart.
