Newsprint, not newspaper
Packing paper is unprinted newsprint. Same stock, same weight, same feel, just taken off the reel before it reaches the press. That single difference is the whole argument, because printing ink does not stay on newspaper. It transfers onto china glaze, onto glass, onto pale wood, onto linen, and onto your hands, and then onto whatever you touch next. You find it again in June when you unpack the last box in the garage.
The counter-argument is that newspaper is free. It is, and if you are packing a shed full of plant pots then use it. For anything you would be sorry to ruin, a ream of clean newsprint costs less than one replacement plate.
Why tissue paper is the wrong buy
Tissue looks like the premium option and is the worst thing on the shelf for a move. Protection in a box comes from two things: a layer between items so they cannot touch, and enough crumpled bulk filling the voids that nothing can shift when the box is carried. Tissue provides the first and none of the second. It compresses to nothing. A box packed with tissue rattles, and things that rattle for forty miles arrive chipped.
Buy large sheets
Around 20 inches by 30 inches is the size to look for. It matters more than it sounds. A dinner plate wrapped in a large sheet gets a full turn plus enough overhang to twist and crumple at the edges, which is what creates the cushion. On a small sheet the paper runs out at the rim, so you reach for a second sheet and end up using more paper for a worse result.
How much paper
A ream of 200 large sheets does an average kitchen. That covers glasses, mugs, plates, bowls, the awkward pans and the contents of the cupboard above the kettle. Add roughly another 100 sheets for a dining room with china and glassware, and 50 more for ornaments, picture frames and the things on top of a bookcase.
People consistently buy half of what they need, run out on the Wednesday and finish the job with tea towels. Tea towels are actually not a bad packing material, but you will want them the following morning to make a cup of tea.
How to use it
Lay a few crumpled sheets in the bottom of the box first. Wrap each item individually rather than in pairs, because two plates wrapped together are two plates that grind against each other. Plates go in on their edge, not stacked flat: on edge, the load runs through the strongest axis and the plate survives what would otherwise crack it. Glasses go upright, never on their side. Then fill every remaining gap with crumpled paper until nothing moves when you tilt the box.
The test is simple. Close the box, pick it up and give it a gentle shake. If you can hear anything at all, open it and add more paper.
