Packing List Generator + Bag Size Estimate

Tell the tool about your trip and it builds a personalized packing checklist — then estimates how many liters it takes up and the carry-on size that fits. Most checklist tools stop at the list; this one also tells you what bag it needs. No signup, nothing to buy.

From trip details to a real list

This tool uses the same packing-volume engine as the PackFitter calculator. It scales clothing counts to your trip length and laundry access, adjusts for climate and packing style, and estimates the total volume in liters — the same number that determines what bag you need. The carry-on size shown is a realistic range, not a promise: shoes, bulky layers, and skipping laundry all push it up.

Frequently Asked Questions

How does the packing list generator work?

Enter your trip length, climate, packing style, laundry access, and clothing size. The tool builds a personalized checklist of clothing and gear based on real clothing volumes, then estimates how many liters your list takes up and the carry-on size that fits it. It does not require a signup.

What carry-on size will my packing list need?

The tool converts your list into an estimated volume in liters and maps it to a typical carry-on range — for example, a 30–40L bag covers most 3–7 day trips for efficient packers. The estimate depends heavily on climate, shoes, and whether you do laundry, so treat it as guidance, not a guarantee.

Does the list tell me if my bag fits a specific airline?

Not in this tool — it estimates the carry-on size range your list needs. To check a specific bag against a specific airline's carry-on and personal-item limits, use the Airline Bag Size Checker.
