Garage beaker panel full, options for adding a dedicated 60A 220V circuit...

I'm of course going to be consulting a pro, but would appreciate some advice so I can at least speak the language and understand what I'm told or offered as solution(s). Panel where I need to add the circuit is in the garage, I do not see any empty spots. My house has three panels: One outside by the meter, one inside in the "old house" and one in the garage that serves the garage and an addition we did about 10 years ago.
The panel is pictured below - not sure if I need a new panel, a sub-panel or something else that I don't know about. Thanks for any help.

I've used double pole breakers, 2 breakers that fit in one slot , to free up slots. You'll need a free slot on each side for a 220 circuit.

Tandem breakers. Double-poles are 240V.
OP, ask the electrician if it's possible to have 4 out of the 5 lower left circuits moved to tandem breakers. Basically those 15-Amp light circuits and the GDO. Leave the water heat circuit as it is. That should give you space for a 60-amp 2-pole providing your panel has the capacity and nothing else needs to be updated to code.

Are you in the BTR area?

You’re adding a 60A 240V to a panel that is only a 100A main and has your ACs and a lot of primary indoor circuits.
Not sure you really have the capacity to do what you want, unless you don’t actually need the 60A. You don’t have to “add everything up”, but this just seems like a lot of load on this panel.

Do you or anyone else here know how to determine when a load is too much for a panel? Or how that is determined. I've done a lot of electrical work, but I've also seen some panels seemingly way overloaded. I know the total draw on the panel at any given time can't exceed the main breaker's size, but do they apply some sort of logic to what can be added? Seems I read that there is always a 20% buffer built into circuits.
I know you won't be running all circuits at the same time. But it's also impossible to prevent people from running ovens heaters, water heaters, and whatever else has high draw at the same time. Was always curious how they determine when enough is enough.
