I was wondering cuz its always a question i ask myself i just put some random trims before departure and arrival but how do you guys actually decide how much trim you put on departure and arrival ?

For takeoff I typically do 20-25 percent, and landing usually 25-35 percent. Really depends on what percent you need

Depends on feel! I prefer 15-20% for most airliners, but you can always choose more or less depending on your preference.
Remember, trim is supposed to help you maintain the correct pitch without struggling. So, really depends on how you calibrate your device, the control setup you use, and what “feels” right

alright thanks for the advice guys

And also, the green line on the trim button tells you exactly what trim you need!

When on final approach with the aircraft completely configured to land, adjust your trim so the green bar disappears. This will give you the perfect trim for landing.
For takeoff, as others have mentioned it depends on the airplane. I’ve found that the reworked airplanes are usually around 15-25% while the legacy airplanes require a lot more, maybe 65-75%.

Every aircraft is different, so it’s impossible to give a specific answer.
I am well familiar with the A359 and for that my personal experience lead me to use 40%.
That’s the same level which I need, when being on final with landing speed.
But different flap configuration and/ or speed and load will change the settings. So it’s more about personal experience. Whatever aircraft you use, try out a bit, check which trim level you need for that type at lowest practical airspeed in landing configuration.
That’s what I set before taking off.
A very rough (and slightly old) guide can be found here:
Some of the quick reference guides for each aircraft on this site has information (I.e. the Max)

The most trim I’ve ever used or will use is in the C-17 between 20-30%. Otherwise for airliners it’s usually less than 7% and for GA less than 15%that’s all for takeoff. Landing can be a little different. The thing to remember with Trim is that all trim is doing is offsetting your calibration up or down by a certain amount. In many cases, what we can achieve with trim can be just as easily achieved without it. It simply can ease our experience. I’d do some trial and error and find what works best for you and the aircraft your using.
I use the Samsung Galaxy S24 Ultra and mainly fly with the B737. During takeoff, I use 20-30% Flap 1 and 5 (VR142~165), and during landing, I use 8-13% Flap 30 (VREF 145~150). I use 15-30% Flap 40 (VREF135~140). I hope this will be helpful when flying the B737.
I’ve used +10% for takeoff and landing on most commercial aircraft, kept the +30% that the Challenger 350 spawns in with, and use +30% on the MD-11 due to its weird center of gravity.
