The Two-Finger Rule: A Simple Safety Check for Your Ties

When it comes to Shibari, one of the most essential (and overlooked) safety tips is something incredibly simple: the two-finger rule. Whether you're a brand-new rope top or a seasoned rigger, this principle is foundational for safe and comfortable rope play.

What is the Two-Finger Rule?

After completing a tie, you should always check to ensure there’s enough space between the rope and your partner’s body by sliding two fingers between the rope and the skin. This simple test helps ensure that:

• Circulation isn’t being cut off

• Nerves aren’t under excessive pressure

• The tie isn’t too tight for the intended duration or position

But this rule doesn’t apply equally to every part of the body—so let’s break it down.

When Tying Ankles, Wrists, or Bony Areas

These areas are more vulnerable because they have less padding. When tying a single column around wrists or ankles:

• You should be able to slide two fingers between the anchor line and the column itself—not just between the rope and the skin.

• This helps reduce pressure on delicate nerves and arteries in these high-risk areas.

💡 Angle matters: Ties like the spiral futomomo naturally shift when tension is applied. The angle of the load can pull the rope upward or downward, tightening the single column anchor and reducing the original two-finger gap. Always anticipate how the rope will move once weight or tension is applied.

Think of it like tying a rope to a vertical pole: change the angle of the rope, and the tightness at the anchor point changes too.

When Tying More Padded Areas

Areas like the thighs, biceps, or torso have more natural padding, which allows for a closer fit without compromising comfort or safety.

• In these areas, the two-finger rule refers to tension, not slack.

• After tying, you should be able to press two fingers under the rope with moderate pressure. It shouldn’t feel loose, but it also shouldn’t feel painfully snug.

Personalization & Consent

Everyone’s body is different. Some rope bottoms prefer a tighter wrap for a more restrictive feel, while others may need a looser fit due to soreness, sensitivity, or just preference.

Use the two-finger rule as a starting point, not a rigid rule. Talk to your partner. Ask for feedback. Adjust as needed.

Final Thoughts

The two-finger rule is one of the most basic yet most effective tools you can use to improve safety in rope. It’s quick. It’s easy. And it shows your partner that you’re attentive, caring, and responsible.

Rope isn’t about tying tight—it’s about tying right.

When in doubt: check your tension, consider your angles, and always make room for two fingers.

When in doubt, cut them out.
