Written Instructions — Square Knot
- Left over right Hold one end in each hand. Cross the left end over the right end and tuck under. Pull snug.
- Right over left Now cross the right end over the left end and tuck under. This is the mirror image of step 1.
- Pull tight Pull both ends to tighten the knot. It should lie flat with two parallel loops.
- Verify it's flat A correct square knot lies flat and symmetric. If one side has a loop and the other doesn't, you tied a granny knot — untie and retry.
Tips for Tying a Square Knot
- The mnemonic: left over right, right over left. Get this backwards and you have a granny knot that slips.
- A square knot is not a bend — never use it to join two ropes you're putting weight on. Use a sheet bend or double fisherman instead.
- The square knot releases easily even after loading by pushing one side toward the center.
- For bandages, the flat profile won't dig into skin like a granny knot would.
