Measuring Your Feet at Home and Choosing the Right Size

How to Measure Your Shoe Size: Measuring Your Feet at Home and Choosing the Right Size

The most reliable way to measure your shoe size is to measure both feet from the back of the heel to the tip of the longest toe while standing on a flat surface with your body weight resting naturally on your feet. The resulting measurement in centimetres should then be compared with the size chart on the relevant product page. Relying solely on the shoe size you usually wear may lead to an incorrect choice because sizing can vary depending on the brand, shoe last, toe shape and heel height.

All you need to measure your feet at home is a sheet of paper, a pencil, a ruler or measuring tape and some adhesive tape. However, factors such as the time of day, the angle at which the pencil is held and which foot is measured can affect the result. In heels intended for weddings, engagements, graduations or long evening events, foot width and how securely the shoe holds the foot should be considered alongside length.

This guide explains how to measure your foot length correctly, compare the result with a women’s shoe size chart and choose the right size for pointed-toe shoes, high heels and special-occasion footwear.

How Do You Measure Your Feet at Home?

To measure your feet accurately, prepare a sheet of paper, a fine-tipped pencil, a ruler or measuring tape and some adhesive tape to secure the paper.

Choose a hard, level surface such as wood, laminate or tile instead of a carpet or another soft surface. If possible, take the measurement later in the day because feet may become slightly fuller after standing and walking.

Follow these steps:

• Secure the sheet of paper to a flat surface so that it cannot move.
• Place your foot on the paper, stand upright and allow your weight to rest naturally on your foot.
• Keep the pencil as vertical as possible and mark the back of your heel and the tip of your longest
• toe. Remember that the longest toe is not always the big toe.
• Measure the straight-line distance between the back of the heel and the longest toe mark.
• Repeat the same process with your other foot.
• If the two measurements are different, use the longer foot when choosing your shoe size.

You can also trace the entire outline of your foot. However, holding the pencil at an outward angle may make the measurement appear larger, while angling it underneath the foot may make it appear smaller.

Marking only the heel and longest toe may therefore provide a more controlled length measurement. Record the result as precisely as possible, preferably in millimetres, because even a few millimetres can make a difference when your measurement falls between two sizes.

What Are the Most Common Mistakes When Measuring Shoe Size?

One of the most common mistakes is measuring the foot while sitting or without placing full body weight on it. When the foot is not bearing weight, its length and width may not reflect how it naturally spreads inside a shoe.

Another common mistake is measuring only one foot. It is normal for the right and left feet to differ slightly in length or width. Choosing a shoe according to the smaller foot may create pressure around the toes or heel of the larger foot.

Other common measuring mistakes include:

• Holding the pencil underneath the foot and making the measurement smaller
• Angling the pencil outwards and making the measurement larger
• Measuring on carpet or another flexible surface
• Using a morning measurement as the only reference for evening footwear
• Measuring from the physical edge of the ruler instead of the zero mark
• Adding an arbitrary one or two centimetres to the actual foot length
• Assuming the same size will fit identically across every brand
• Comparing the foot with the full outside length of the shoe

If the size chart is labelled “foot length”, compare it with your actual heel-to-toe measurement. Do not add extra space unless the brand specifically instructs you to do so. The required allowance is generally already considered when the shoe last and size chart are prepared.

How Do You Determine Shoe Size from Foot Length?

Once you have measured the length of your longer foot, compare it directly with the size chart provided by the brand you intend to purchase from.

General online formulas may provide an approximate result. However, the same EU size can feel different between brands and even between different styles produced by the same brand. For this reason, the size chart and fit information on the specific product page should take priority over general conversion formulas.

The general size references displayed on Tacchi product pages are as follows:

This table should be used as a general guide. Before placing an order, check the available sizes, fit description and any model-specific recommendations on the relevant product page.

A “true to size” description generally means that customers can begin with their usual shoe size. If a product is described as having a narrow fit or includes a special sizing recommendation, that information should take priority over the general chart.

If your measurement falls between two sizes, do not automatically choose the smaller or larger option based on length alone. Foot width, toe shape, the amount of coverage and how securely the straps hold the foot should also be considered.

Does Shoe Size Change When Choosing High Heels?

Heel height does not change the actual length of your foot, but it affects how your foot sits and moves inside the shoe.

As the heel becomes higher, more weight shifts towards the forefoot. This may cause the foot to slide forwards, particularly in open-toe or single-strap styles.

A shoe that is too large can increase movement and cause heel slippage. A shoe that is too small can compress the toes or cause the forefoot to extend beyond the front of an open shoe.

In a correctly fitting pair of heels:

• The heel should not leave excessive space.
• The straps should secure the foot without creating concentrated pressure.
• The toes should remain within the sole.
• The shoe should not slip noticeably while walking.

A suitable gel insole or heel grip may help if there is only a small amount of extra room. However, these accessories should be used to refine the fit of a correctly selected size, not to compensate for a shoe that is clearly too large.

When choosing evening shoes, test them on a clean surface by walking, turning and standing for a short period. This will make it easier to understand whether your foot slides forwards, whether the straps create pressure and whether the heel lifts while walking.

Should Your Toes Reach the End of Pointed-Toe Shoes?

No. Your toes are not expected to fill the visible tip of a pointed-toe shoe completely.

The pointed section is partly a design extension, and the natural toe area sits further back inside the shoe. For this reason, measuring the full outside sole from the heel to the pointed tip and comparing it with your foot length may produce an incorrect conclusion.

The fit of a pointed-toe shoe should be assessed by checking whether:

• The toes overlap or feel compressed
• The ball of the foot is under sharp pressure
• The foot is squeezed from both sides
• The heel slips noticeably while walking

A visible empty section at the very tip does not necessarily mean that the shoe is too large. However, if the forefoot is being compressed from the sides or the toes are forced together, the width or shape of the shoe last may not suit your foot.

When ordering pointed-toe bridal shoes, consider both your foot length and forefoot width. Do not choose an unnecessarily smaller size simply because your toes do not fill the pointed tip.

How Should Wide, Narrow or Half-Size Feet Be Fitted?

Shoe size primarily communicates length, but length is not the only factor that determines fit. Two people may have the same foot length while one has a wider forefoot and the other has a narrow, low-volume foot.

Closed shoes that narrow significantly towards the front may feel tighter on wider feet. However, sizing up solely to gain extra width can create too much space at the heel and cause the shoe to slip while walking.

Before changing sizes, consider:

• The toe shape
• The shoe material
• The position of the straps
• Whether the model is open or closed
• The product’s specific fit description

If necessary, measure around the widest part of your forefoot and request advice about the specific style.

For narrow feet, open or strappy shoes may feel loose even when the length is correct. Adjustable ankle straps, slingback styles and suitable gel insoles can help the foot remain more secure inside the shoe.

If you usually wear a half size and the brand does not offer half sizes, the correct decision will depend on the model. Choosing the smaller size and expecting it to stretch is not a reliable method because different materials have different levels of flexibility.

In many cases, the larger size can be assessed with a thin gel insole. However, narrow lasts, open sandals and slingback styles may fit differently, so model-specific advice should be requested.

What Should You Check When Buying Shoes Online?

When shopping online, avoid relying only on statements such as “I always wear a size 38” or “I am usually a US 8.”

Use the following checklist before ordering:

• Measure both feet later in the day.
• Record the measurement of the longer foot.
• Compare the result with the size chart on the product page.
• Check whether the model is described as true to size, narrow or wide.
• Consider whether the style is pointed-toe, platform, slingback or single-strap.
• Request model-specific advice if your feet are wide, narrow or between sizes.
• Read reviews carefully and look for customers who mention their foot length or foot shape.
• Check the delivery, exchange and return conditions before purchasing.

Special-occasion shoes should be ordered early enough to allow time for fitting and assessment before the event.

Once the shoes arrive, keep the outsole protected and test them indoors on a clean surface at different times of the day. If you are wearing a long wedding dress or evening gown, take the selected shoes to your hem fitting so the length can be adjusted according to the actual heel height.

Frequently Asked Questions

Is it better to measure your feet in the morning or evening?

Measuring later in the day generally provides a more realistic result because feet may become slightly fuller after standing and walking. This is particularly useful when choosing heels or occasion shoes intended for an evening event.

What should I do if one foot is larger than the other?

Choose your shoe size according to the longer foot. If the shoe on the smaller foot has a small amount of extra space, a suitable heel grip or thin gel insole may help improve the fit.

How much room should there be at the front of a shoe?

There is no single visible gap that applies to every shoe design. Your toes should not feel compressed or be pushed firmly into the front while walking. In pointed-toe shoes, it is normal for part of the extended tip to remain unfilled.

Should high heels be one size smaller?

No. Automatically choosing a smaller size because the foot may slide forwards can create pressure around the toes and forefoot. Begin with your measured foot length, the product’s size chart and its fit information.

How much should I add to my foot length?

If the product chart asks for actual foot length, do not add an arbitrary amount. Allowance systems differ between manufacturers. Only add extra space when the brand’s instructions specifically require it.

Can women’s shoe size change over time?

Yes. Foot measurements can be affected by age, pregnancy, weight changes and changes in foot structure. Even if you have worn the same size for years, measuring again before an important purchase can help you make a more accurate decision.

The most reliable starting point for finding the correct shoe size is your current foot measurement rather than the size label you have always worn. Measure both feet while standing, use the longer result and compare it with the size chart for the exact product.

For heels and special-occasion shoes, consider not only length but also forefoot width, how securely the style holds the foot and how the shoes feel while walking.
