What Size Is a Large Suitcase? A Beginner-Friendly Guide

Whether you're gearing up for a two-week European getaway or packing for a family vacation, choosing the right suitcase size can make or break your travel experience. If you're wondering, what size is a large suitcase, and when should I use one?—you're in the right place.

In this guide, we’ll break down what “large” really means in luggage terms, how it compares to medium suitcases and trunk sizes, and how to choose based on your travel plans. Plus, we’ll feature some of our top DELSEY PARIS picks in the large category.

What Counts as a Large Suitcase?

In general, large suitcases are designed for checked luggage and are ideal for trips lasting 7 to 14 days or longer.

• Height: 27"–30" (68–76 cm)
• Width: 18"–21" (45–53 cm)
• Depth: 11"–13" (28–33 cm)
• Capacity: 75–110 liters

These bags are made to hold bulkier items like boots, jackets, full-size toiletries, or multiple pairs of shoes—while still fitting within the maximum size limits for checked luggage on most major airlines.

✈️ Tip: Most airlines have a 62 linear inch limit (height + width + depth) for checked bags. Learn more from the TSA’s official guidelines and check with your airline before flying.

Large vs. Medium vs. Trunk: What’s the Difference?

Here’s how a large suitcase compares with medium suitcases and trunk-style luggage:

When to Choose a Large Suitcase

Here’s when going “large” makes sense:

• Long vacations (1–2 weeks or more)
• Multiple travelers sharing one suitcase
• Winter trips requiring coats, boots, and layers
• Shopping or gifting during travel
• Cruises or overseas travel with few laundry options

For lighter packers or shorter trips, a medium suitcase might still do the job. But if you're unsure, it’s better to have the extra space—especially if you’re bringing home souvenirs.
