Unique Industries (brand)

Unique makes a wide range of licensed and themed cone hats and crowns in multi-packs that match its own tableware, so a theme is easy to complete.

Not for: Adults wanting sturdy, reusable headwear like metal tiaras or felt crowns that last beyond one party.

Beistle (brand)

I'd choose Beistle for festive party headwear with classic designs suited to birthdays, holiday celebrations, and themed gatherings.

Not for: Anyone seeking protective headwear or premium everyday hats.

Rhode Island Novelty (brand)

Rhode Island Novelty sells tiaras and crowns in bulk packs suited to handing one to every guest.

Not for: Brides or anyone wanting a keepsake-quality tiara.

Beistle (brand)

Beistle is a long-running US maker of paper party hats and tiaras with classic New Year's and holiday designs.

Not for: Toddler parties where a soft, strap-free option is preferred.

Chin strap. Look for an elastic strap that is already attached and stapled, or knotted, at both sides. Loose or missing elastic is the most common complaint, and hats that slide off get abandoned within minutes.
Sizing. Match the cone height and base diameter to the wearer. Child-sized cones look odd on adults and adult cones topple on toddlers. Listings often mix kid and adult sizes without flagging the difference.
Assembly. Prefer pre-formed hats, or flat hats with a pre-scored tab, over flat sheets that need taping. Assembling a dozen or more flat hats before a party takes real time.
Small parts for young children. For guests under 3, avoid pom-poms, glitter and glued gems that can detach. Detachable decorations are a choking hazard.
Material. Heavier paperboard or foil board keeps its cone shape. Thin paper creases flat in a bag or on a head. Crushed hats look bad in photos, and photos are the main reason people buy headwear.

Are party hats one size fits all?

Usually not. Cone hats come in child and adult heights, so check the listed dimensions before buying for a mixed-age group.
