My personal advice is: Do not throw rumpled clothes in there chaotically.
Most people fold their dried clothes of the same type (trousers, shirts, towels and so on) to the same size in order to stack them neatly in their wardrobe. In my experience the default folding technique works best in suitcases as well. Use this to fill your suitcase with neat stacks.
Depending on your suitcase, figuring out where to put which stack might resemble a game of Tetris at first. The rules are very simple:
- Put the biggest items in first and fill gaps with the smallest items
- Put heavy and insensitive items (that can be rumpled) at the bottom (where the wheels are).
- Put fragile or sensitive items in the middle of the suitcase. (This is because suitcases get thrown around. Fragile items should be as far away as possible from any outside surface.)
- If you need to fold items in half to fit the suitcase, you must fold each item individually or you waste a lot of space.
Start by taking the clothes you want to pack out of your wardrobe and put them in stacks onto a surface like your bed.
Row 1:
- Start at the bottom of the suitcase (where the wheels are) with heavy items that fill the width of it as best as possible. In my case that's always a stack of trousers. If you want to pack towels, fold them to fit the width of the suitcase and place them here as well.
- On top of that, stack items that are not prone to rumpling, like t-shirts or jumpers, until they reach the top of the current half of the suitcase. Usually 2 stacks of them next to each other should fit the width of the suitcase.
Row 2:
Above that (further away from the wheels) put sensitive clothes that are prone to rumpling or that you need to stay neat.
The rest of the t-shirts or jumpers that didn't fit into row 1 go on top of that.
Put any lightweight clothes (like jackets) on top of that to fill the depth of the suitcase and cushion the sensitive items.
- If you have any fragile items, put them in between the cushioning
Row 3:
- Put any lightweight items like caps, hats, bras or flip flops on top
Gaps:
- Fill the gaps between the neat stacks of clothes with underwear or swimwear. You'll always find enough nooks to cram your underwear in without reserving space for it.
