At least 3 in. drain pipe
The standard size of a toilet flange is typically 4 inches in diameter.
depends on the size of drain piping. Most toilet either have a 3" or 4" drain. The size hole needed would be larger than the outside diameter of the piping. 3" pipe=4" hole / 4" pipe=5" hole
Probably the wrong size flange. Is the flange a toilet collar? If so the pipe is probably 4 inch.
depending on your type of flange and pipe and the damage of the flange, if you have a PVC flange with just the bolt slots busted then you can screw in new bolts to the floor below the flange and still use the flange but if its broken where the wax seal sits then if your flange is lower then the floor you can use a insert flange that fits inside your old toilet flange with thin walls to keep the pipe size maximum. To replace the entire flange can be a job especially if its in concrete or in a floor joist because most of the time you have no room and if its cast iron pipe it can be even more of headache but in order to replace the flange you need to cut it out to where you can reconnect the pipe and flange by using a fernco or a no hub band. Sometimes it is impossible to replace because the flange can be on all close fittings and you pretty much have to replace most of the plumbing drain pipe to replace it properly which is why you want to try repairing your toilet flange rather then replacing it .

It depends on the flange used and how hard it is to move the supply line. Without looking at the job it is impossible to tell. Some toilet flanges have a second mounting point 90 degrees apart, others can have the screws taken out and the mounting ring can then be turned 90 degrees, some have no provision for movement. You would have to remove the toilet to see what you have. If the flange cannot turn or it is in too bad condition (rusted out) you will have to replace it or use a flange repair ring. it depends on the circumstances. If there is room to put an extention flange on it would be easy. if not it depends on your pipe size running to the toilet, if the bottom of the flange is accessable or many other factors.
Any vent is usually the size of the drain or waste pipe it is connected to. 3 or 4 inch on a toilet.

To secure a toilet lid properly, you will need plastic or metal toilet lid screws that are typically size 10-24 or 10-32. These screws are designed specifically for attaching toilet lids securely to the toilet bowl.
1. Loosen the 2 nuts that are located on each side of the toilet. Place them in a safe location, because you will need them to remount the toilet.2. Lift the toilet. Set it in a place where the rest of the water can drain from it, such as a shower or bathtub.3. Clean the wax from the flange seal, and then remove the screws that attach it to the floor.4. Measure the pipe that comes out of the floor so that you purchase the correct size. You will need to buy a new flange, a new section of pipe with the same diameter as the old pipe, a pipe coupling, a new wax ring and PVC glue if you do not have any.5. Cut off the flange at the red line. This can be done, from inside the pipe, using a Dremel tool with a reinforced disk for cutting.
according to hole dia and flange thickness we divide the dia and length of bolt. normally 1.25 less in dia and 1.25 add in length
To measure the ASA (American Standards Association) size of a pipe flange, you need to determine the nominal pipe size (NPS) and the flange's pressure class. Measure the outside diameter of the flange and the bolt circle diameter. Additionally, count the number of bolt holes and measure their diameter. These dimensions help identify the correct ASA flange standard for compatibility with piping systems.
