Choosing the right vehicle scale is about more than simply weighing a vehicle. The right option depends on what you’re weighing and what you need to measure. Whether you’re checking a caravan before a holiday, weighing a trailer or checking vehicle weight for work, choosing the right type of scale helps ensure you get the measurements you need.
Understanding the different types of vehicle scales and what they measure can make that choice easier. If you’re unsure what you need, the Safety Dave team can provide practical advice based on your vehicle and how you plan to use the scale.
What Will You Be Weighing?
The first step in choosing a vehicle scale is understanding what you need to weigh. A caravan or trailer owner may need to check individual wheel loads, axle weights or overall vehicle weight, while someone towing may also need to check tow ball weight.
Vehicle scales can be used for:
- Cars and SUVs
- Caravans and camper trailers
- Boat and equipment trailers
- Motorhomes
- Commercial vehicles
Once you know what you’re weighing and which weight measurements you need, it’s easier to determine which type of scale is suitable.
Portable Vehicle Scales or a Weighbridge?
One of the most common questions buyers ask is whether they need portable vehicle weighing scales or a permanent weighbridge for vehicles.
Portable vehicle scales and fixed weighbridges serve different purposes. Portable scales can be moved between locations and generally require minimal setup, making them useful when vehicles need to be weighed in different places or when a permanent weighing system isn’t practical.
A weighbridge is permanently installed and is generally better suited to businesses that weigh larger vehicles regularly from the same location. It requires dedicated space and a significantly greater investment than a portable scale.
The right choice depends largely on the vehicles being weighed, how often weighing is required and whether the equipment needs to be portable.
What Accuracy Should You Expect?
Vehicle weighing scales are designed to provide accurate and repeatable measurements when used correctly.
For caravan and trailer owners, accurate readings can help identify how weight is distributed and whether the vehicle is loaded within the appropriate limits. For commercial users, reliable weight measurements can assist with vehicle safety, load distribution and operating within relevant weight limits.
Accuracy will depend on the type of scale, its capacity and how it is used, so it’s important to follow the manufacturer’s instructions and use equipment suited to the vehicle being weighed.
What Factors Should You Consider Before Buying?
Before choosing a vehicle scale, consider:
- What type of vehicle you need to weigh
- The maximum weight you need to measure
- Whether you need a portable or fixed solution
- How often the scale will be used
- Ease of transport and storage
- Durability
- Calibration and servicing requirements
- Australian product support
Considering these factors will help you choose a vehicle scale that is suitable for your needs.
Choosing the Right Vehicle Scale
There is no single vehicle scale that suits every application.
If you need to check individual wheel loads or axle weights, a Wheel Ramp Scale may be the right option. If you’re checking the tow ball weight of a caravan or trailer, the SD 400kg Tow Ball Weight Scale provides a simple way to measure the downward weight placed on the tow ball.
The right choice comes down to what you’re weighing and which weight measurements you need. If you’re unsure, the Safety Dave team can help you work out which option is suitable for your vehicle or towing setup.
Make an Informed Choice
Choosing the right vehicle scale comes down to understanding what you’re weighing, the measurements you need and how you’ll use the scale. Taking these factors into account will help you choose equipment that is suitable for your needs.

Common Questions About Vehicle Scales
What is the difference between wheel weight, axle weight and overall vehicle weight?
Wheel weight is the load carried by an individual wheel. Axle weight is the combined load carried by the wheels on an axle, while overall vehicle weight is the total measured weight of the vehicle. Looking at these measurements can also help identify how weight is distributed across the vehicle.
Do I need to weigh each wheel separately?
Not always. Weighing each wheel separately can be useful when you want to understand how weight is distributed across a vehicle, caravan or trailer. Individual wheel measurements can help identify differences in load from one side to the other and can also be used to determine axle and overall weight
Should a vehicle or caravan be loaded before it is weighed?
Yes. If you want to understand the weight of a vehicle or caravan as it will be used on the road, it should be weighed in its normal travelling condition. This means including the passengers, luggage, equipment, water and other items you would normally carry. This provides a more realistic measurement of the vehicle or caravan’s loaded weight.
How often should vehicle scales be calibrated?
Calibration requirements vary depending on usage and manufacturer recommendations. Businesses using vehicle scales regularly should have them checked periodically to maintain consistent accuracy.
Are vehicle scales suitable for heavy trucks and machinery?
Yes, some vehicle scales are designed for heavy trucks and machinery. The scale must have the appropriate weight capacity and be suitable for the type of vehicle being weighed. Always check the scale’s specifications before use.
