About King Size

King Size has specialized in big and tall menswear since 1920, carrying only extended sizes. You'll find fits that standard retailers often don't stock, with tops well into the double-X range, waists past 70 inches, and extra-wide shoes in hard-to-find sizes. It belongs to the FullBeauty family of brands, so one account, card, and rewards balance carries across all of them.

For help with shipping, returns, or an order, call 1-800-955-2236 or send a request from their contact page. To place an order by phone, call 1-800-846-1600.

King Size returns and how to avoid the $10.99 fee

King Size charges $10.99 to refund a return to your card, but you can get all your money back by taking a gift card or making an exchange instead. The gift card never expires and works across every FullBeauty brand, so the only downside is having no plans to shop those stores again. An exchange waives the fee, too, and a straight size or color swap on the same item ships back free either way.

Timing is the part people miss, since the clock starts earlier than you'd expect. Your return has to arrive within 60 days of the day the order shipped, not the day you send it, so a package that sits around can blow the window even when you mailed it on time.

Hemming is the one cost you can't recover, because that charge doesn't come back once a garment is altered. It's smart to hold off on alterations until you're sure you're keeping something.

So before you ship anything back, take the gift card or an exchange to hold onto your $10.99, and send your return early enough to clear the 60-day arrival window.

Frequently asked questions about King Size

The King Size Platinum Card earns rewards points faster

The Platinum Card is a store credit card, not a coupon, so it won't take money off at checkout on its own. What it does is earn points faster and unlock a few cardholder-only perks, and the part most shoppers miss is how much faster.

For most people, the welcome offer is the real reason to open it. New cardholders save $20 on a first purchase of $25 or more, as long as the whole order goes on the card. On a small first order, that's the best deal the card ever hands you, so time it for something you were going to buy anyway.

Past that bonus, the card earns slowly, and the rate is its real edge. Cardholders get 15 points per $1, double the 10 the free rewards program gives everyone else. It's the same program either way, so the card just moves you to a $10 certificate, which takes 3,000 points, in half the spending. You also get a birthday reward each year and free shipping a handful of times a year on larger orders.

The catch the sign-up page won't lead with is the high interest rate. Carry a balance even a single month and the interest can wipe out a year of points, welcome bonus included.

That's why the card hinges on paying in full. Clear the balance each month and the $20 welcome deal plus the doubled points add up fast. Carry one and the interest outruns every point you earn, canceling the only reason to hold the card.

King Size Rewards pays more the more you spend in a year

King Size Rewards is a free loyalty program, and the earn rate climbs the more you spend in a year. You join through a King Size account, not by signing up for emails, and there's no fee to be a member.

Everyone starts at Silver and moves up by spending more across a calendar year.

  • Silver earns 10 points per dollar

  • Gold earns 15 points per dollar

  • Elite earns 20 points per dollar

So a regular shopper earns back twice as much per dollar at the top as a casual one does at the bottom. When your points reach 3,000, they convert to a $10 rewards certificate.

The tiers come with more than a faster rate. Every member gets a birthday reward, and the program runs double-point events through the year that move you toward that next certificate more quickly. Reach the Elite tier, and you also unlock free standard shipping on qualifying orders a few times a year. Shopping other FullBeauty brands adds to the same points balance, which helps you climb tiers sooner.

The real draw is that the program rewards you for being a regular rather than handing out a one-time deal. A shopper who orders steadily earns Elite-level points on purchases, but a casual buyer would still be banking at the Silver rate.

Joining costs nothing, so there's no downside even on a single order a year. Your points sit and wait with no charge to hold them, and you build toward that first certificate from your very first purchase.
