PackFitter
Packing Calculator & Fit Tool
Plan. Pack. Fly.
Some links on PackFitter are affiliate links. This page explains what that means, how it works, and why it doesn't change the recommendations you see.
PackFitter may include links to products on Amazon and other retailers. When you click one of these links and make a purchase, PackFitter may earn a small commission from the retailer. This is how many independent websites fund their work.
These commissions come from the retailer, not from you. The price you pay is exactly the same whether you use an affiliate link or go directly to the retailer's site.
Recommendations on PackFitter are based on real packing capacity, airline fit, and how well a bag matches the trip type being discussed. We do not recommend products because they pay higher commissions or because a brand asked us to.
If a bag appears on the site, it's because it fits the criteria for that page — capacity, dimensions, and practical use. Affiliate partnerships do not influence which products are shown or how they are ranked.
We believe in being upfront about how the site works. Affiliate revenue helps keep PackFitter running and free to use. Being transparent about it is the right thing to do, and it's required by the FTC and by affiliate programs like Amazon Associates.
If you have questions about any product recommendation or link on the site, feel free to reach out.
