40th Birthday Party Themes, Decorations & Supplies — 40th Birthday Ideas

Ah, the Big 4-0. The transition from young adulthood into... Sigh... Party City believes that all birthdays should be heartily celebrated, and your friend's 40th birthday milestone is no exception. Is he or she looking forward to an exciting new chapter in the book of life? And do you, the host of the bash, need a few 40th birthday ideas to help the party theme along? Our 40th birthday supplies, 40th birthday decorations, and 40th birthday favors are all about the exciting and inevitable next decade of adulthood! Do you mourn the passing of youth? Our 40th birthday gag gifts help ease the passage of time (maybe) — at the very least, they offer a reason to laugh. Browse the categories of tableware for 40th birthday party ideas; you can purchase one of our kits, or personalize the celebration by creating a theme all your own. Custom banners are one of the very best ways to announce a birthday message — these 6-foot long decorations command the party scene with a message personlized for the 40th birthday victim... er, guest of honor. Look for these in decorations, or in each of our 40th birthday themes shown above. Some custom banners even allow you to upload a photo of the birthday boy or girl — what a great keepsake when the party's done! Cake supplies may be an afterthought, but consider just how important these really are, because a 40th birthday cake is little more than a glorified muffin until the cake toppers line up to sing happy birthday and and the oversized candles light up. So start your 40th birthday shopping at Party City, where the birthday themes are affordable and abundant, and where birthdays never go out of style!
