How to Build a Rope Railing in 6 easy steps

June 27, 2022

Introduction

Building a rope railing is a beautiful way to add a classic nautical theme to your outdoor landscaping. You can find rope handrails near beaches, and waterfronts, along with decks and docks, as a stair railing, or landscaping around a home. 

In this article, we’ll teach you how to easily build your very own rope railing. We’ll include what materials, and tools, you’ll need as well as pro tips to make sure your project comes out beautifully. We also recommend checking out our in-depth YouTube videos, where we cover everything you need to know.

Planning Your Rope Railing Project

Step 1) Choosing the Right Rope

The first thing to consider when planning for your rope railing project is to decide what kind of rope to use. If you want to go with a nautical theme, we recommend promanila rope (aka Unmanila rope) hands down. In some cases, you’ll see the use of natural fiber manila rope, but we recommend against using any natural fiber ropes. This is because natural fiber ropes deteriorate quickly outdoors, resulting in a shorter lifespan. Below is a table comparing our four recommended types of Ropes, and their average life span. Note that these are estimations and will vary depending on your environment. 

Type of Rope:Average Life Span:
Manila (Natural)5-10 years
Promanila/Unmanila (Synthetic)10-15 years
Nylon15-20 years
Polyester 25-30 years

Step 2) Choosing your mounting technique/design

Rope railings come in many varieties, from traditional round posts, and wrapped ties, to more modern square posts with cut-out passthrough holes. This is your opportunity to pick a design and mounting technique that works for your aesthetic, budget, and toolkit. There isn’t a “best” style here, but here at Right Rope, we recently built a rope railing, with square posts, and cut-out passthrough holes, and loved the results.

It is important to know that depending on your mounting technique the amount of rope you’ll need will vary. Wrapping the rope around each railing, for example, will increase your rope’s required length.

Step 3) Choosing the correct Post Sizes and Rope Diameter

If you are using 4-inch wood posts, we typically recommend you choose a 1 ¼-inch diameter or 1 ½-inch diameter rope. If you are using 6-inch wood posts, we recommend 1 ½ inch diameter or 2-inch diameter. And if your posts are larger than 6 inches, we recommend our largest size of promanila rope, 2 ½ inch diameter rope.

For this project, the customer chose 6-inch wood posts and 2 ½-inch promanila rope. Other possibilities would be 2-inch or 1 ½-inch rope, but this 2 ½-inch looks awesome! 

Step 4) Calculating the length of Rope(s) you’ll need

You may choose to anchor your rope halfway through the end posts. Another option is to tie the rope off on the outside of the post, or you could hang the rope on the outside of your posts using hardware. The amount of rope you will need depends on which style you choose. When making this calculation, also remember to add for sag in between each post. If you choose to use natural fiber manila rope, be sure to add 10-15% to account for shrinkage.

Step 5) Install / Attach the rope to the end posts

In our project, we drilled holes through each of our posts using a hole-saw, and a drill. It’s important to note that the actual diameter of the Promanila rope is slightly larger than the listed diameter. You’ll want to make sure to account for this and drill a hole that is big enough to feed your rope through.

Right Rope Pro Tip: Drill your post holes at least 1/4 inch bigger than the listed diameter of your rope

Once we feed the rope through each post, accounting for the desired sag, we attached the rope to our terminating post with lag screws.

Step 6) Sit back, and enjoy your new rope railing!
