Are most common washers in tap half inch?

Ah! So the spout is different?!

Doesn't matter - almost certainly half-inch :-)

Might be worth a dry-run first - make sure the valves are easy to remove? Then you can confirm the size, and lightly replace the valve - it'll be super-easy to remove when you get the parts.

I'd add a tube of silicone grease to your arsenal - give the washers a smear, ditto the threads and O ring on the valve. And if your tap isn't turning smoothly, it might also be the opportunity to sort that - easy to do, and it'll transform the way the tap operates.

Happy you know the sequence? Plenty YouTube vids, and we can guide too.
