Here’s A Simple Guide to Picking the Right Car Jack Size
Knowing the size of your car jack matters just as much as the type. In this article, you’ll learn about the four main types of jacks and how to pick the right size based on your car’s weight, ground clearance and make. You’ll get tips on matching jack capacity and height to your vehicle, so you stay safe and ready. Plus, we’ll help you figure out what works if you own more than one car.
Don’t waste money on a jack that won’t work for your vehicle. If it’s the wrong size, it’s just cash down the drain.

What Are the Main Types of Car Jacks?
Before picking a size, let’s go over the four main types of car jacks. Choosing the right type first makes it much easier to figure out which size you need. Here’s a quick breakdown:
Floor jacks
Aluminum floor jacks – also called trolley, garage or service jacks – are made for garages and workshops. They’re too big and heavy to keep in your trunk, so they’re not great for on-the-go use.Bottle jacks
Bottle jacks get their name from their bottle-like shape. They’re simple to use and strong, often lifting up to 50 tons, so they’re great for trucks and other heavy rides.High-lift jacks
Got a farm or off-road vehicle? A high-lift jack is a smart pick. Just pump the handle and you’re good to go. It’s really that easy.Scissor jacks
Last but not least is the popular scissor jack. It’s small and light, so you can always keep one in your trunk without any trouble. Scissor jacks are super convenient, but they’re only good for tire changes. Don’t use one to check under your car since it’s not built to hold weight for long.
So, What Size Jack Do You Need for Your Car?
The jack size you need depends on your car’s weight and how high it sits off the ground. Here’s what to keep in mind when choosing the right one:
The jack’s capacity
A simple rule is to get a jack with a lifting capacity that matches your car’s weight. To stay safe, pick one rated for at least 75% of your car’s weight. You’ll find your vehicle’s weight in the owner’s manual.Height
The tallest jack that still fits under your car is usually best. Floor jacks are about 5 cm high, so they slide easily under low areas. Bottle jacks are taller (about 20 cm) so they’re better for higher spots like frame rails. To check if a jack will fit, just measure the space from the ground up to where the jack would go under your car.Your car’s weight
To get the right jack, you’ve got to know your car’s weight. Heavier vehicles will require a jack with a greater weight capacity. If you drive a sedan, a 4-ton jack is a solid pick since most sedans weigh 2 to 3 tons.Your car’s make and model
For sedans, especially with low suspension, floor jacks work best. Trucks do great with bottle jacks, while high-lift jacks are ideal for off-road vehicles.
Got more than one type of vehicle? You’ll probably need different jacks to match each one.
What Can Go Wrong If You Use the Wrong Size Jack?
Using a jack that’s too small or not rated for your vehicle’s weight can lead to serious safety hazards. An undersized jack may collapse under the vehicle’s weight, causing the car to fall unexpectedly, which can result in injury or damage. It may also fail to lift the vehicle high enough for maintenance tasks, making it ineffective. Always check the jack’s weight capacity and ensure it matches or exceeds your vehicle’s curb weight before use.
What Are Common Mistakes When Picking Jack Size?
One of the most common mistakes is selecting a jack based on appearance or general use rather than the specific weight and clearance needs of your vehicle. Some people also forget to factor in the load from cargo or modifications, such as lift kits. Failing to use jack stands in conjunction with the jack is another critical safety error. Always consult your vehicle’s manual and consider your lifting needs before purchasing or using a jack.
Are Smaller Jacks Less Durable Than Bigger Ones?
Not necessarily. Jack durability depends on build quality, materials and weight rating rather than size alone. A well-made compact jack rated for your car can be just as reliable as a larger one, as long as it’s used within its intended limits.
