Many travellers struggle with finding a large enough space to pack all of their clothes, electronics, and other travel necessities. While this predicament could be easily solved by buying a monstrous sized suitcase, most travellers prefer not to rent a moving truck to transport their incredibly over sized suitcase to the airport.
For the rest of the travel world with normal sized suitcases, luckily, there are a few easy ways to free up valuable packing space in your suitcase.
Storing Within
“Storing Within” is most likely the easiest way to free up space. Simply pack any light clothing items, such as socks, underwear, gloves, or small hats into other items already in your suitcase, such as shoes or even water battles. Moving these smaller items into other items will free up plenty of space for larger, bulkier items.
Roll Em’ Up
After a number of studies focused on finding the optimal packing method, travel experts agree rolling your clothes, rather than folding, saves much more space in your suitcase. Rolled clothes take up much less space in your suitcase than a large pile of folded clothing. Roll up and carry on.
Satellite Luggage
Many travellers tend to pack their most valuable and more important clothing items in their primary suitcase. An easy way to free up space in your primary suitcase is to move smaller, less important clothing into your satellite luggage, such as a computer bag, briefcase, or camera bag. Moving items such as socks into other luggage will help free up space for your other larger or more important items, such as your big floppy sunhat. 
Travelling Companion
The “Travelling Companion” method  is very simple and helpful in freeing up more room in your suitcase. If you’re travelling with a friend, a family member, or any other traveling companion, ask them if they have any extra room in their suitcase they won’t be using and move a few items into their suitcase. While this method seems extremely obvious, many people may not think that their travelling companion might just have a little bit of extra space for some of your items.
