What counts as a large convention?

On Costumary, large conventions draw between 20,000 and 50,000 attendees. They are big enough for major industry guests and events, but smaller than mega cons like SDCC or Dragon Con.

How should I plan for a large convention?

Book your hotel 3 to 6 months in advance, buy badges as soon as registration opens, and plan your schedule before you arrive. Large cons have enough going on that you need priorities. Use the convention budget calculator and packing checklist to prepare.

Are large conventions better than mega conventions?

Different, not better. Large cons have shorter lines and less sensory overload while still offering major guests and events. Mega cons have unmatched energy and scale. It depends on what you want from the weekend.

How much should I budget for a large convention?

A realistic weekend budget is $400 to $700 including badge, hotel, food, and spending money. Splitting a hotel room with friends cuts the biggest expense significantly.
