As a guide, allow 100 ml of gravy per adult (normal appetite).
Quick calculator
For a roast dinner, a good rule of thumb is about 100ml of gravy per person. That covers a plate generously without swimming.
How much to make
- Light: ~75ml each
- Normal: ~100ml each
- Hungry / gravy lovers: ~150ml each
- Child: ~60ml each
So for a family of four, aim for around 400–500ml of gravy. It’s the one thing at Sunday lunch nobody minds having extra of — especially if there’s mash, Yorkshire puddings or roast potatoes to mop it up — so making a bit more than the maths suggests is never a bad idea.

How this is worked out
For a roast dinner, allow about 100ml of gravy per person as a sensible average. Gravy is one thing people rarely complain about having too much of, so for a Sunday roast — especially with mash or Yorkshire puddings to soak it up — it's worth making extra.
