Building a Cat Scratching Post? Use Our Rope Length Calculator to Get It Right!

If you’ve ever tried building your own cat scratching post, you know the struggle: “How much rope do I actually need?” Do you buy too much and end up with leftovers? Too little and end up rage-cutting zip ties and starting over?

We’ve solved that with our Custom Rope Calculator for Cat Scratchers—a tool you won’t find in many places (trust me, we looked).

🧰 Here’s what it can calculate:

  • 📏 Total height of the scratching post
  • 🔄 Diameter of the post (yes, including wrap-around logic)
  • 🧵 The rope thickness (¼”, ⅜”, ½” etc.)
  • ✅ Automatic estimate of how much rope you’ll need in feet
  • ⚠️ It even tells you how many feet per coil or spool if you want to match to standard store-bought rope bundles

It’s ideal for:

  • DIYers building a custom post for their cats
  • Budget-conscious builders trying to avoid waste
  • Pet lovers who want the right scratch without the guesswork

This tool was designed by cat people, for cat people—because nothing’s worse than getting halfway through a build and realizing you’re 6 feet short of sisal.
