How to Measure Arch Height at Home: Low, Normal, and High Arches

Understanding Arch Types

Your foot arch is the curved structure along the inside of your foot, from the heel to the ball. The height of this arch affects how your foot absorbs impact and transfers weight. There are three general categories: low (flat feet), normal, and high arches.

Flat feet, also called fallen arches, have little or no visible arch. The OrthoInfo resource from the American Academy of Orthopaedic Surgeons lists flatfoot as a recognized condition. High arches show a pronounced curve and place more weight on the ball and heel of the foot. Both conditions can influence how you stand and walk, and the kind of footwear that feels comfortable.

Most people have a normal arch, which provides a balanced distribution of pressure across the foot. However, arch height can vary from one person to another and even between your own two feet. Understanding your arch type is the first step to choosing shoes that support your natural gait and prevent discomfort.

The Wet Test: Step-by-Step

The wet test is a quick way to estimate your arch height. You only need water and a flat surface that shows damp marks. Here is how to do it:

• Step 1: Wet the sole of your foot with water. Make sure it is damp but not dripping.
• Step 2: Step onto a sheet of paper, a paper bag, or a concrete floor. Stand normally so your full weight is on the foot.
• Step 3: Lift your foot and step away. Look at the print you left behind.
• Step 4: Compare your print to common arch patterns: a full footprint suggests a low arch, a visible inward curve suggests a normal arch, and a very narrow connection between the forefoot and heel suggests a high arch.

The Tape Measure Method

If you want a more quantitative measurement, you can use a flexible tape measure to measure the height of your arch. This method gives you a number in centimeters or inches, but keep in mind there is no single correct value. The interpretation depends on your foot length and overall anatomy.

To measure, sit in a chair with your foot flat on the floor. Place the tape measure at the floor, directly below the highest point of your arch, then extend it vertically to the top of your arch. Read the measurement. Repeat for both feet, as arches can differ.

Write down the measurements and compare them to typical values, but remember that a normal range varies widely. For a more complete picture, you can also trace your foot on paper and measure the length and width.

How Arch Height Affects Shoe Support Needs

Your arch height determines how much support and cushioning you need from your shoes. People with low arches tend to overpronate, meaning the foot rolls inward excessively. They benefit from stability shoes with firm midsoles and arch support to control motion.

People with high arches often have a rigid foot that absorbs shock poorly. They need soft, cushioned midsoles and flexible outsoles to help with impact absorption. Those with normal arches can usually wear a balanced range of shoes with moderate support.

Choosing the right shoe for your arch type can prevent foot pain and other issues. Explore our guides on choosing shoes for high arches and choosing shoes for flat feet, or read about the different arch support types to match your needs.

Shoe Features for Your Arch Type

Once you know your arch type, look for specific features in your footwear. For low arches, a shoe with a straight last and a firm heel counter helps control pronation. You might also consider a shoe with a removable insole so you can insert custom orthotics if needed.

For high arches, choose a curved last and a well-cushioned midsole. A softer platform absorbs impact and reduces stress on the heel and ball of the foot. Look for shoes labeled with extra cushioning or a soft ride.

If you have normal arches, you have the most flexibility. Look for shoes that feel comfortable and provide a moderate amount of support without feeling too stiff or too soft. You can also rotate between different types of shoes depending on the activity, such as walking, running, or casual wear.

Limitations and When to See a Podiatrist

Home methods give a rough idea, but they are not diagnostic. If you experience persistent foot pain, discomfort, or notice a visible change in your arch, consider seeing a podiatrist. A professional can perform a more thorough gait analysis and recommend appropriate footwear or orthotics.

The American Podiatric Medical Association emphasizes that your feet are your foundation for a healthy and happy life. If you have concerns about your arch structure, a podiatrist can help address them.

Remember that arch height is just one piece of the puzzle. Foot width, toe length, and the shape of your heel also matter when selecting shoes. Our shoe width explained guide and heel height measurement article can give you a fuller picture of your foot anatomy.

What to Pick for Your Use

Questions

Can I measure my arch height without wetting my foot?

Yes. You can use a tape measure to measure the distance from the floor to the top of your arch while standing. Alternatively, you can check the wear pattern on an old pair of shoes: excessive wear on the inside edge may indicate low arches, while wear on the outer edge may indicate high arches. These methods are less precise than a professional evaluation but can give you a general idea.

How accurate is the wet test?

The wet test is a simple screening tool that provides a visual estimate of your arch height. It is not a medical diagnosis. For a precise assessment, a podiatrist can use pressure plates or gait analysis. However, for most people, the wet test is a helpful starting point when choosing everyday shoes.

What if my footprint looks like a combination of two types?

It is common to have different arch heights between your left and right foot. You may also fall between categories. In that case, choose a shoe that matches the foot that requires more support, or buy shoes that allow for removable insoles so you can adjust one side separately.

Do I need to see a doctor if I have flat feet or high arches?

Not necessarily. Many people with flat or high arches do not experience problems. If you have no pain and your shoes fit comfortably, you usually do not need treatment. But if you have foot, ankle, or knee pain, or if you notice your symptoms worsening, a podiatrist can help.

Can arch height change over time?

Yes, arch height can change due to aging, injury, pregnancy, or conditions like posterior tibial tendon dysfunction. If you notice a sudden change in your foot shape or arch height, or if you feel instability when walking, consult a medical professional.

Are there any other home methods to determine arch height?

Besides the wet test and tape measure, you can look at the wear pattern on your shoes. If the inside of the heel or forefoot wears down quickly, you likely have low arches. Wear on the outside edge suggests high arches. You can also stand on a hard floor and have someone observe your ankle alignment from behind. A significant inward roll indicates overpronation, common with low arches.
