title: "What Size Mug Should You Buy?"
lead: "300–350 ml (10–12 oz). It holds a standard coffee pour with room for milk, and you finish it while it's still hot. Go larger only for lattes or slow desk sipping."
recommendation:
  name: "A 300–350 ml (10–12 oz) mug"
  reason: "A standard 240 ml (8 oz) pour plus milk fits with margin, and you empty it before it cools. If you sip for an hour or more at a desk, add a ~450 ml insulated mug as your second."
