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.
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.

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.
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.
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.
