Bifold Wallet

Fold a wallet once down its long edge and you get two inner faces looking at each other, three or four card slots on each, and a single full length pocket running behind both for notes. Closed, the body lands near 4.5 inches wide and 3.5 inches tall; open, it spans about 9 inches. A US bill at 6.14 inches long lies flat inside instead of being folded a second time.

Every card gets counted twice, once in its slot and again at the spine when the wallet shuts. Six cards split three and three stay manageable; six stacked on one side wedge the fold open and the wallet stops closing square. Better makers stagger the slots so cards overlap by two thirds, and skive the hide, meaning shave it thinner, along the fold line. Slot stitching settles the rest of the lifespan, since slots sewn individually to the panel behind them keep their grip for years. A row cut from one folded piece stretches all at once.

Where a trifold takes the same cards and folds them into half the width at three times the depth, this stays wide and flat, so it disappears in an inside jacket pocket and prints across a trouser pocket. Card cases skip notes and coins entirely to stay under a quarter inch. Zip around wallets contain everything and want two hands and a bag. Watch for a vertical bifold as well, folded across the short edge: the slots run the same way. But the note pocket is only about 4 inches long, so bills have to be folded before they go in.

Five or six cards plus daily cash is the load this shape is proportioned for, which describes most people who still carry paper money. Jacket wearers get the most out of it, since a flat wide object sits invisibly in a breast pocket. Rethink it at nine cards, because forcing two into one slot stretches the leather within months and it never grips again. Back pocket carry is the other reason to hesitate: half an inch of wallet under one side of your pelvis tilts you every time you sit and dries the leather with body heat.

Open a candidate flat and run a finger along the note pocket to confirm it reaches corner to corner, since a short pocket is the most common shortcut here. Load it with your real cards and shut it, because every wallet closes flat when empty. Backstitching at the mouth of each slot, the doubled stitches that stop leather splitting outward, is worth looking for, as is a thumb notch on the outer slots. Empty it monthly and leave it open overnight, since leather sets around whatever it is asked to hold.
