What tool do I need for bike pedals?

My pedal sizes are 9/16 but confused what tool to get to remove them.

If the axle has flats you need a 15mm open end wrench Some pedals are removed with a allen wrench.

Not all 15mm wrenches are thin enough to work on pedal flats, there are specific made pedal wrenches like the Parktool PW-3, 4 or 5 that work well

I've done the allen wrench thing, and soak them with some kind of lube over night. I've cracked a few knuckles trying the allen wrench thing.

Bought a pedal wrench, life is easy again!

Some pedals have only the hex socket (Allen is a trademark), a square drive hex bit and breaker bar will save your knuckles. I have a crowfoot wrench which is thin enough to fit pedal flats, also used with a breaker bar.
Edit: Allen 20574

More importantly turn them the correct direction. They are both different

As mentioned not all pedals have wrench flats, only a hex socket, 8 mm if you are lucky, 6 mm if your not. You need an extra long hex wrench or a hex bit in a 3/8" square drive ratchet to protect your knuckles

There are some pedals that have wrench flats too narrow even for a dedicated pedal wrench. For example, MKS detachable pedals have couplers that mount on the cranks and the flats are too narrow for a Park pedal wrench. There's no hex fitting. Luckily, a 15mm cone wrench works perfectly.

Get a cheap caliper and you can measure yourself.

Park Tool PW-1 or Park tool PW-3 will do 9/16 pedals. Here is a video showing them.

Forget the clockwise/counterclockwise, left/right stuff. Tighten toward the front of the bike. Loosen toward the rear.

Same spatial orientation trick I use for adjusting spoke nipples. Visualize the spoke nipple from looking down at the top of the wheel. Tighten and loosen as we would any ordinary threaded connection.

That's an open end wrench. (double)
A Crescent wrench (Brand name) is typically an adjustable open end wrench.

In addition to the many suggestions, if a pedal is being stubborn, I will support the end of the crank with wood blocks from the floor, so I can push down really good on the wrench. I've never had to fight a pedal more than once because I clean and grease the threads before re-installing.

If a pedal has both wrench flats and an opening for an allen wrench, I will sometimes use both to get a little extra torque. I put the allen wrench and 15mm wrench on so they are approx. 180 degrees then set the bike so the rear wheel is held in place (on the ground) and set the crank so my loosening action will push the pedals forward. This way the chain holds the crankarm in place and you only need half the torque on each tool, which can save you from slipping and jamming your knuckles into the chainring.

You could also, if you have a stout wrench that fits on the wrench flats (good pedal wrench) set the bike on the ground and align the crank and wrench so pushing down on the wrench will loosen the pedal, then push down on the wrench with your foot.

I had a dude who ruined my long cone wrench by using it to try and get a stuck pedal off a crankarm. Yeppers, he sprung the opening of the wrench.
