23 - 24 Small Checked Luggage These sizes are popular for travelers looking for a smaller, lighter option of luggage to check. These pieces are too large to carry onto the plane, but are perfect for trips of 3 to 5 days. There is room for 2 to 3 outfits, a couple pair of shoes, and toiletry kits.

A 24-inch "medium" suitcase is the versatile workhorse of the luggage world, typically offering enough capacity for a 7-to-10 day trip. Using standard packing methods, you can comfortably fit approximately 5-7 complete outfits, including 2-3 pairs of pants, 7-8 shirts, a lightweight jacket, and 2 pairs of shoes (one worn, one packed). This also includes enough space for a week's worth of undergarments, sleepwear, and a toiletry bag. If you utilize the "Rolling" or "Ranger Rolling" method combined with compression packing cubes, you can often push this capacity to 10-12 outfits, making it viable for a two-week vacation if you plan to do a light load of laundry. Because this size usually requires being checked rather than carried on, you don't have to worry as much about liquid limits, allowing you to pack full-sized essentials. The key to maximizing this suitcase is "mix and match" versatility—packing items that can be layered or reworn in different combinations—ensuring you have plenty of variety without the bulk of a 28-inch "large" case.
