Size guide & measuring advice

Measure carefully once, then compare your measurements with the relevant chart to choose shoes, clothing or jewellery with confidence.

Important: sizing and fit information on the individual product page always takes priority. Model, material and cut can affect the fit.

Shoe sizes

Measured foot length is more reliable than a size worn in another brand. The conversion below applies to adult adidas footwear.

How to measure your feet

In the evening, stand on a sheet of paper wearing the socks you plan to use.
Place your heel against a straight wall, distribute your weight evenly and mark the tip of your longest toe.
Measure the straight distance from the wall to the mark in centimetres.
Measure both feet and use the larger result in the chart.

Fit tips

If your measurement falls between two chart values, choose the next value up for more room.
Wide feet, thick socks and extended wear may require extra space.
The heel should feel stable while the toes must not touch the front.

adidas kids’ shoes

Children’s feet grow quickly. Measure both feet while standing and check the length regularly.

Clothing & textiles

Measure close to the body over light clothing. Keep the tape horizontal without pulling it tight. Chest guides tops; waist and hips guide bottoms.

How to take body measurements

Chest: measure horizontally around the fullest part.
Waist: measure around the narrowest part without holding your stomach in.
Hips: keep feet together and measure around the fullest part.
Inseam: measure vertically from the crotch to the floor.
Height: stand straight and barefoot, then measure from head to floor.

If your measurements point to different sizes, use the largest relevant body measurement, especially for close-fitting garments.

adidas kids’ clothing

The numeric size usually corresponds to the child’s height. Age is only a guide; actual measurements are more accurate.

Jewellery sizes

A few millimetres can change the comfort. Use a flexible tape or non-stretch string, then check the string against a ruler.

Find your ring size

EU ring size equals the inner circumference in millimetres. An inner circumference of 54 mm therefore means size 54.

Two reliable measuring methods

With a well-fitting ring: measure the inside diameter across the centre from inner edge to inner edge.
Without a ring: wrap tape or string where the ring will sit, mark the overlap and measure it in millimetres.
Measure at the end of the day at a normal temperature and repeat twice.

EU	US	UK	Inside Ø (mm)	Inside circumference (mm)
44	3	F	14.0	44
46	3 3/4	G 1/2–H	14.6	46
48	4 1/2	I 1/2	15.3	48

54	6 3/4	N	17.3	54
56	7 1/2	O 1/2–P	18.0	56
58	8 1/2	Q 1/2	18.5	58
60	9	S–S 1/2	19.3	60
62	10	T 1/2–U	19.7	62
64	10 3/4	V–V 1/2	20.4	64
66	11 1/2	X	21.0	66
68	12 1/4	Y 1/2	21.7	68
70	13	Z+1	22.3	70

Wide bands usually feel tighter than narrow ones. If you are exactly between sizes, the larger size is often more comfortable.

Bracelets & bangles

Measure your wrist where the bracelet will sit. In a label such as L15, the number refers to the inner circumference in centimetres. A “v” often indicates an adjustable length.

Choose the preferred fit

Wrap the tape closely around the wrist without pressure.
Add the allowance shown below for your preferred fit.
For a rigid bangle, also confirm that your hand fits through the opening.

Fit	Add to wrist
CloseSits close to the wrist.	+ 0.5 cm
ComfortableEasy everyday movement.	+ 1.0 cm
LooseMoves visibly; avoid excess room with heavy charms.	+ 1.5–2.0 cm

Choose a necklace length

The same length looks different depending on neck size, build, neckline and pendant. Measure an existing necklace flat or test the length with string.

Length	Typical position
35–40 cm	Close to neckChoker or collar effect.
42–45 cm	CollarboneVersatile everyday length.
50 cm	Upper chestWorks with small to medium pendants.
55–60 cm	Mid chestLonger look and easy layering.
70–90 cm	Long necklaceStatement or layering length.

A pendant makes the necklace hang visually lower. For clear layering, use lengths that differ by roughly 5 cm or more.

Watches & watch straps

Wrist circumference controls the fit; case diameter mainly affects the visual proportions. Product-specific strap and case measurements remain decisive.

Compare wrist and case

Measure where the watch will sit, normally just behind the wrist bone.
Keep the tape against the skin without tightening it. Add about 0.5–1 cm for a relaxed fit.
Compare the result with the strap length and check whether metal links can be adjusted.

Case diameter as a visual guide

Case	Visual effect
up to 34 mm	Compact and discreet
35–39 mm	Medium and balanced
40–44 mm	Bold and sporty
45 mm and up	Very prominent; check lug width too

Frequently asked sizing questions

What should I do if I am between two shoe sizes?

Choose the next chart value up for more toe room and also check any model-specific fit notes and sock thickness.

Why measure feet in the evening?

Feet can expand slightly during the day. Measuring in the evening reduces the chance of choosing a shoe that is too tight.

My feet are different lengths. Which measurement counts?

Use the longer foot. The shorter foot can be secured with lacing or an insole if needed.

What do adidas sizes such as 38 2/3 mean?

adidas uses one-third size steps. Compare foot length directly with the chart instead of rounding to a whole EU size.

How tight should the tape be for clothing?

Keep it horizontal and close to the body without squeezing or hanging loose. Measure over very light clothing.

Which size should I choose for a wide ring?

Wide bands often feel tighter. If you are on the boundary, the next size up is frequently more comfortable.

Can ring size change during the day?

Yes. Temperature and activity affect finger circumference. Measure at a normal temperature and repeat the measurement.

What does “v” mean in a bracelet size?

On many jewellery pieces, “v” indicates an adjustable length. The exact adjustment range is shown on the product page.

Is age enough to choose a kids’ size?

Age is only a guide. Height, foot length and measured circumferences are more reliable.

What if the chart differs from the product page?

The individual product description, label and model-specific fit note take priority over a general chart.
