1. Everyday Guidance & Final Verification
ScaleAndFit is provided free of charge to help estimate sizes accurately. While all geometry, 300-DPI dimensions, and public datasets are carefully maintained, rules change periodically across agencies and brands.
2. Official Passport & Visa Rules
Always review the current photo guidelines published by your embassy, passport agency, or visa portal (for example lighting, glasses restrictions, or recent photo age limits) before final submission.
3. Airline Fare Tiers & Baggage Sizers
Carry-on cabin and under-seat allowances depend on ticket fare class and carrier updates. Measure bags including wheels and handles and verify your booking confirmation before traveling.
4. Footwear & Ring Fit
Individual shoe models, sock thickness, and wide/narrow ring band styles affect comfort. Use brand millimeter equivalents and card-calibrated ring measurements alongside retailer sizing advice.
