How to Choose the Right Zipline Kit: 15m, 30m, 45m, 60m, 75m or 90m?

Choosing the right zipline kit is about more than simply measuring the distance between two trees. The correct zipline length, cable, anchors, slope, braking system and rider equipment all need to work together.

At Cable-Ride.com, we have been specialising in zipline equipment since 2013. Our goal is simple: provide reliable, properly selected equipment and practical advice so you can build a zipline that is fun, durable and appropriate for its intended use.

This guide explains how to choose between 15m, 30m, 45m, 60m, 75m and 90m zipline kits and what you should consider before buying.

1. Start with the available distance

The first question is straightforward:

How much usable distance do you actually have?

Measure the distance between the proposed start and landing points. However, do not automatically choose a kit with exactly the same length as your measured distance.

A zipline requires space for:

• the cable installation
• the anchor points
• the required slope
• the rider's travel
• the braking system
• a safe stopping and dismounting area

For example, if the available distance is approximately 32 metres, a 30m kit may be appropriate depending on the installation conditions. If you have substantially more space, a 45m, 60m or longer system may be more suitable.

The available distance is therefore the starting point — not the only factor.

2. Which zipline length should you choose?

Cable-Ride.com offers complete zipline kits in several lengths. The best option depends on the available space and the intended use.

15m zipline kit

A 15m zipline is a compact solution for smaller gardens and installations where space is limited.

It can be suitable for:

• smaller private gardens
• children and family use
• compact recreational installations
• situations where a long run is simply not possible

The shorter cable length also makes the installation easier to accommodate in a smaller area.

30m zipline kit

A 30m zipline is a popular choice for a larger garden or recreational installation.

It provides noticeably more travel distance than a 15m system while remaining relatively compact.

A 30m kit can be a good choice when you want:

• a family garden zipline
• more riding distance
• a relatively straightforward installation
• a balance between installation space and riding experience

45m zipline kit

A 45m zipline is a versatile option for larger gardens and recreational installations.

At this length, installation planning becomes increasingly important. Cable selection, anchoring, tension and braking should be considered as one complete system.

For customers looking for a longer family or private installation, a 45m system can offer an excellent balance between size and performance.

60m zipline kit

A 60m zipline requires considerably more space and should be planned carefully.

At this distance, factors such as:

• cable sag
• elevation difference
• cable diameter
• rider weight
• braking
• anchor strength
• installation geometry

become increasingly important.

A 60m zipline can provide a significantly longer and faster-feeling ride, but the installation should be properly assessed rather than simply extending a shorter system.

75m zipline kit

A 75m zipline is intended for larger installations where substantial travel distance is available.

At this length, professional planning becomes increasingly valuable. The cable, anchors, tensioning system and braking system should be selected as a coordinated system.

The available elevation difference is particularly important because a longer cable does not automatically mean that more slope is required.

90m zipline kit

A 90m zipline is a large recreational installation requiring significant space and careful planning.

For installations of this size, we recommend paying particular attention to:

• cable specification
• anchor construction
• cable tension
• rider weight
• elevation
• braking distance
• clearance
• installation and inspection

A 90m system should not be treated simply as a longer version of a small garden zipline.

3. The cable is one of the most important components

The cable is the structural element that carries the rider and trolley system.

Cable-Ride.com supplies zipline cable in different diameters and specifications, including 6mm and 8mm galvanised aircraft-grade steel cable.

The correct cable depends on the complete installation rather than simply on the length of the zipline.

Important considerations include:

• cable diameter
• construction
• breaking load
• installation length
• rider weight
• tension
• anchor configuration
• expected use

Never select cable solely because it is visually thicker or because it has been used on another installation.

The complete system needs to be considered.

4. Don't forget the anchors

A strong cable is only useful if the cable is properly anchored.

Depending on the installation, anchoring may involve:

• suitable trees
• structural posts
• engineered structures
• tree protection systems
• slings
• cable clamps
• thimbles
• shackles or connectors
• tensioning equipment

When using trees, protecting the tree and ensuring that the attachment method is appropriate are important considerations.

A tree saver or suitable sling can help distribute the load and avoid unnecessarily damaging the tree.

The anchor points should always be assessed for the loads generated by the installation.

5. What about the slope?

A zipline normally requires an elevation difference between the start and finish.

However, there is no single universal slope that is suitable for every zipline.

The required geometry depends on factors such as:

• cable length
• rider weight
• trolley type
• cable tension
• starting height
• braking system
• desired riding speed
• installation environment

Too little elevation can result in insufficient travel speed.

Too much elevation can result in excessive speed and substantially higher braking requirements.

This is why the installation geometry should be considered before fixing the final anchor heights.

6. Braking is essential

A zipline needs a reliable way of reducing the rider's speed before the end of the cable.

Cable-Ride.com offers several braking components, including bungee braking systems and stop blocks.

A passive bungee brake works by progressively absorbing the rider's kinetic energy as the trolley reaches the braking zone.

The correct braking configuration depends on the installation.

Factors include:

• rider weight
• riding speed
• cable length
• cable slope
• trolley type
• available braking distance
• number and configuration of bungee elements

For longer or faster installations, braking deserves particular attention.

Never assume that a braking system suitable for one zipline will automatically be suitable for another.

7. Complete kit or individual components?

For a straightforward installation, a complete zipline kit can be the easiest solution.

A complete kit can bring together the main components required for the installation, such as:

• zipline cable
• trolley/pulley
• harness or seat
• handles
• anchoring components
• braking components

However, experienced installers may prefer to select individual components.

This can make sense when:

• replacing an existing component
• upgrading an installation
• building a custom zipline
• adapting an existing cable
• installing a longer system
• selecting a specific trolley or harness
• designing a professional or specialised installation

Cable-Ride.com also supplies individual zipline components for customers who do not require a complete kit.

8. Which harness should you choose?

The rider's equipment is just as important as the zipline itself.

Depending on the rider and intended use, options can include:

• standard zipline harnesses
• comfort harnesses
• children's harnesses
• seats
• handles

The harness should be appropriate for the rider and compatible with the trolley and connection system.

For children, correct sizing and supervision are particularly important.

A comfortable harness can also make a significant difference during longer rides or repeated use.

9. Children or adults?

Before choosing a kit, consider who will use it.

A zipline designed primarily for children may have different requirements from one intended for teenagers and adults.

Consider:

Rider weight

The complete system needs to accommodate the intended rider weight.

Rider height

Harness fit and connection geometry can vary between users.

Riding experience

A beginner-friendly installation may require a different approach from a high-speed recreational system.

Supervision

Children should be appropriately supervised and should only use equipment suitable for their age, size and ability.

Braking

The braking system must be appropriate for the actual rider and installation.

10. How to choose the right zipline kit

As a simple starting point:

Available installation	Possible kit
Small garden	15m
Medium garden	30m
Large garden	45m
Large property	60m
Very large installation	75m
Large recreational installation	90m

This table is only a starting point.

The available distance, elevation, anchors, cable specification and braking system must always be assessed together.

11. What should you measure before ordering?

Before purchasing a zipline, collect the following information.

Distance

Measure the horizontal distance between the proposed anchor points.

Height

Measure the available height at both ends.

Anchor type

Determine whether you are using:

• trees
• wooden posts
• steel structures
• concrete structures
• another engineered support

Rider

Determine the expected minimum and maximum rider weight.

Intended use

Is the zipline for:

• children
• family use
• adults
• private recreation
• commercial/recreational use?

Braking area

Make sure there is enough space for the chosen braking method and a safe stopping area.

These measurements will allow you to make a much better decision than simply selecting the longest kit that fits your garden.

12. Why buy from a zipline specialist?

Zipline equipment is a specialist product.

Since 2013, Cable-Ride.com has focused specifically on zipline systems and components rather than treating ziplines as one product category among thousands of unrelated outdoor products.

That specialist approach allows us to focus on:

• cable selection
• trolley and pulley systems
• harnesses
• braking
• anchoring
• tensioning
• installation considerations
• replacement components

We believe customers should be able to buy equipment based on clear technical information rather than marketing claims.
