Knots reduce the overall strength of a rope. Any bend tighter than 4” reduces the strength of rope because they stress the rope in flexure, the fibers' weaker direction.

.

Hereof, do different types of knots affect the breaking strength of a rope?

A very good & important question! Yes, it does to a significant extent! The world-known bowline e.g. reduces the strength of the individual rope by 40(!)

Similarly, how strong is a square knot? Square (reef) knot. One of the best known knots for tying together two lines of equal diameter. Notice the symmetry--both free ends are on the same side of knot. It's a relatively weak knot--breaking strength is only 45% of rated line strength.

Similarly one may ask, what is the strongest knot for rope?

The strongest tie-in knot you can use is the figure-eight follow-through, which, when pull-tested, breaks at 75 to 80 percent of the rope's full strength. The bowline is a slightly weaker knot, at 70 to 75 percent, followed by the double fisherman's at 65 to 70 percent.

What is a good strong knot?

Clove Hitch A hitch is a knot that connects a rope to an object. The clove hitch is a simple but important survival knot that's easy to tie. The benefits you get from it are that it doesn't loosen or slip, and you can lengthen or shorten the rope without untying the knot.
