Basic Question: What’s the Ideal Luggage Weight Limit for Budget Airlines?​

I'm always perplexed by the ever-changing luggage rules on budget airlines. It feels like the "ideal" weight limit is a moving target depending on the airline and even the specific route. Generally, aiming for under 7kg for carry-on seems like a safe bet, but that can be incredibly restrictive, especially if you're traveling for more than a weekend or need to pack shoes.

For checked baggage, it seems like pre-booking a 20kg allowance is often the sweet spot – enough to pack essentials without breaking the bank with extra fees at the airport. does anyone else find themselves doing a mental inventory of everything they're packing and weighing items on a kitchen scale before a budget flight? What weight limits do you typically target and what's your strategy for staying within them?
