Family Halloween costumes need one theme available across adult, child and infant sizing. Expect $30 to $60 per person for a coordinated set. Every result here is a live retailer listing, so you can check each family member's size and price before ordering.
One theme, every size. These matching family looks cover adults, kids and the smallest member of the crew.
Pick a theme that has a natural role for every age, including one for a baby who will be in a carrier or pram. Themes drawn from animated films, classic monsters and food groups tend to have the widest sizing coverage across retailers. Check that the theme still works if one person opts out at the last minute.
Buy the hardest size first — usually the infant or the tallest adult — and build the rest of the family around whatever theme has that size in stock. Children's costumes should fit over a warm layer for evening trick-or-treating, and adult versions of children's themes are often cut noticeably slimmer than expected.
A family of four typically spends $120 to $220 in total. Costumes built around matching t-shirts, hats or face paint over normal clothes bring that down to well under $100 and are much easier to wear for a full evening.
Order everything in one go in early or mid-October so sizes stay available across the set. If one piece is delayed, you still have a coordinated group; if it's the theme's key piece, you need time to substitute.
