The Crib to Campus Packing List: What Actually Matters for Move-In Day
Every August I get some version of the same message. Kid's moving into residence in two weeks, no idea where to start, and every packing list online has forty items on it, half of which nobody actually uses. Fair. So here's the short version, from someone who sells this stuff and has strong opinions about what's worth the money.
The one sizing thing that trips everyone up
Almost every Canadian and U.S. residence room ships with a Twin XL bed, about 39 inches wide and 80 inches long, five inches longer than a regular twin. Ontario mattress retailer Mattress Miracle confirms it's the standard at schools like McMaster, Mohawk, and Conestoga, and Sleep Foundation's dorm sizing guide backs up the same Twin XL default across North America. That extra five inches matters more than it sounds like it should: a regular twin fitted sheet will pop off the corners within a week, because it's fighting length it doesn't have.
So: sheets and mattress pads need to say Twin XL on the label. Not "twin." Not "twin, close enough." Twin XL, specifically.
Duvets are the one exception, and it trips people up in the opposite direction. Go up to a Queen duvet cover even on a Twin XL bed. Fifteen inches of drape on either side looks like a blanket someone threw over a mattress. Twenty-five inches looks like a made bed. That's the whole reason the Queen duvet covers are the ones we point people to for a Twin XL room. It has nothing to do with the mattress size.
What's actually worth buying
The Waterproof Quilted Mattress Pad in Twin XL ($30) is the one I'd never skip. Dorm mattresses have a long, complicated past by the time your kid gets one, and it protects both the mattress and the security deposit. It's quilted, not the crinkly plastic kind, so it doesn't feel like sleeping on a pool float.
For sheets, the 4-Piece Bedsheet Set in Twin XL ($24) covers the basics, or the Luxury Twin XL Sheet Set, 600TC percale cotton blend ($37.99), if you want something that actually feels nice after the fortieth wash. Either way, buy two sets. Laundry access in residence is unpredictable, and nobody wants to be sleeping on a bare mattress pad because the one set they own is in a machine three floors down.
Then a Queen duvet cover for the drape reason above, and if the room runs cold, the Caramel Rosette Sherpa Blanket ($22) at the foot of the bed earns its keep fast.
If you'd rather not build this piece by piece, the Dorm Bed Bundle ($48) covers Twin XL sheets and the mattress pad together, or the Premium Dorm Bed Bundle ($60) if you want the 600TC sheets in that same bundle. The Campus Starter Bundle ($115) goes further and covers the whole bed plus a bag, which is the one I'd point you to if you want to buy this in one sitting and never think about it again.
The bag part
A laptop actually needs to survive the walk across campus in October, so this isn't the place to go cheap on zippers. The Roll-Top Laptop Backpack ($45) is the one I'd start with, it's a proper roll-top, so it expands when the day involves a gym bag or a grocery run, not just textbooks. The Expandable Roll-Top Laptop Backpack in black ($45) is the same idea in a color that won't show every mark by October.
What I'd skip
Decorative throw pillows. They take up packing space and every dorm room ends up with them on the floor by week two. A second duvet insert, one is enough if you're washing the cover regularly. And I wouldn't bother with a twin, not XL, anything. It will not fit, and you'll be re-buying it in September anyway.
The short version
Twin XL for sheets and the mattress pad, Queen for the duvet cover, two sets of sheets minimum, and a backpack that can survive four years, not four weeks. Everything above lives in the FLY Residence collection if you want to see it side by side, and the Campus Starter Bundle is there if you'd rather just hand someone a bag and be done with the whole thing.
Every order still gets checked by me before it ships, so if something's off, I catch it before move-in day does.
