It will depend on what type of fishing you are doing!On average 1/8 to 1/4 oz for most soft plastic's will work well and if you need to peg a piece of cut bait to a river bottom it may be a 1 oz to even 6oz's of lead.With surf casting you can start with a 1 oz then move up to more if needed.But to fully answer the type of fishing and waters fished are needed to give full answer!
Ledger
A downrigger is a fishing tool which uses a heavy weight "4-8 ounces, normally" to get your bait or lure down to the depth where fish are found "see using your depth/fish finder" at trolling speeds. The fishing line and bait are attached to a thin stainless steel line which the heavy weight is attached to. Your fishing line and bait are then, held in place to the stainless line and weight by a quick re-release clip. When a fish takes your bait the clip releases the line your poll snaps up, somebody on the boat yells..."fish on!" and then the battle begins! It is physically impossible to get your bait to depths of 75-100 or more feet down without the use of a down rigger at trolling speeds.
line
To put on a fishing hook properly, first tie a fishing knot to the end of your fishing line. Then, slide the eye of the hook onto the knot and pull it tight. Make sure the hook is securely attached to the line before baiting it and casting your line into the water.
A backlead is an additional weight on a fishing line, which ensures that the line rests on the bed of the lake.
Called a "trot line".
The Ledger is simply a weight that is attached to the end of a fishing line. For fishing it is essential that the main line from a reel is terminated in a hook length of line that is of slightly lesser strength ie mainline 12lb and terminal line 10lb. This ensures that if the fish breaks the line it is not dragging a long length around the lake. The set up is simple, we have the main line attached to the weight with a second hook length off the weight with some bait on it. The hook length is of lesser strength. Often a 'hair rig' will be used. This is where the bait used is attached to the hook by a few millimetre of line. This encourages a fish to take the bait without feeling the hook. There are many ways of attaching the hook line to the ledger or main line such as a 'helicopter rig'. I suggest readers do a google search for 'helicopter rig', 'hair rig', 'knotless knot' and ledgering..... regards.... Rufty in Kent
It is called a fly

In typesetting, the thickness of a line is called its weight and is measured in points.
Anchor rode, safety line or a mooring line.
Well, there are spinnerbaits. Which is kindof like a jig head with a skirt kj it and attached to it is a bent wire that runs parallel to the hooks and on the wire is usually 2 or 3 blades, this is the main type for bass fishing. There is also another slumber called a rooster tail which is small metal bait with a blade attached near where the line is tied to.
