How many glasses per person at a party?

Each guest needs a glass for each drink type they will have. Typically: 1 wine glass, 1 water glass, and possibly a champagne flute for toasts. Allow 15% extra for breakages and people setting down glasses and getting a fresh one.

Do I need different glasses for red and white wine?

For formal events, yes - red wine glasses are larger and rounder. For casual parties, one style of wine glass works for both. If hiring, standard wine glasses are versatile. Stem-less wine glasses are trendy and less likely to be knocked over.

How many champagne flutes for a toast?

One per person who will toast. Not everyone drinks champagne - some will toast with their current drink. For weddings, order flutes for all guests. For casual parties, 70-80% of guests is usually enough.

Should everyone get a water glass?

Yes. Every guest should have a water glass regardless of what else they are drinking. Water glasses also double as soft drink glasses. This is especially important at events serving alcohol.
