OMP First-S suit sizing: where to start at 180cm and 85kg
A customer asked which OMP First-S size to choose at 180cm and 85kg. Size 54 is a useful starting point, but those figures also fall within size 52 on OMP's chart. We need the body measurements before making the buying call.
Garreth would get the tape out before ordering. Cameron would check chest, waist, hips and inside leg against the same size, then look at the remaining measurements and how the suit feels in the driving position.
Start with the measurements for sizes 52 and 54
Height and weight overlap; a chest reading alone does not confirm the whole fit.
- Size 52: 170–183cm, 75–85kg and 103–107cm chest
- Size 54: 177–187cm, 83–88kg and 107–111cm chest
- Compare waist, hips, inside leg and the remaining body measurements
- OMP advises the larger size when you fall between two sizes
OMP's racing suit size chart, sizes 44 to 64
Use OMP’s current racing-suit size guide with your body measurements in centimetres and weight in kilograms. The First-S listing offers sizes 44 to 64, which are the rows shown here.
Height and weight help narrow the search. Waist, hips and leg length still matter, even when your chest sits neatly inside one band. Compare the complete row before choosing.
Scroll across to compare every measurement; the size column stays in view.

OMP lists body measurements, not garment measurements, and advises the larger size when you fall between two.
Where 180cm and 85kg lands on the chart
Both 52 and 54 include 180cm and 85kg. The weight is at the upper edge of the 52 band and inside the 54 band. We still need the customer’s chest, waist and leg measurements to compare them properly.
The 56 row starts at 85kg, although 180cm is below its published 182–190cm height band.
| Size | Height (cm) | Weight (kg) | Chest (cm) | 180cm and 85kg |
|---|---|---|---|---|
| 52 | 170-183 | 75-85 | 103-107 | Height inside the band, weight at the top edge |
| 54 | 177-187 | 83-88 | 107-111 | Height and weight both inside the band |
| 56 | 182-190 | 85-92 | 111-115 | Weight at the bottom edge, 180cm below the height band |
Cameron would compare a 103–107cm chest with the 52 row and a 107–111cm chest with the 54 row, keeping waist, hips and inside leg alongside them. At the shared 107cm boundary, OMP’s guidance is to choose the larger size.
Garreth would treat 54 as a provisional recommendation for this question until the measurements and a try-on support it.
How to measure yourself for a race suit
You need a flexible tape and, ideally, someone else to hold it. OMP says to measure while wearing your racing underwear, because the garment layer changes the chest and waist readings. Stand relaxed with your arms by your sides.
- Chest (A): round the fullest part, under the arms, with the tape level across your back.
- Waist (B): round your body at belly button height.
- Hips (C): round the widest point of your buttocks.
- Thigh (D): round the thigh, 5cm down from the groin.
- Arm (E): from the shoulder point to the wrist.
- Inside leg (F): from the groin to the ankle bone.
- Shoulders (G): from one shoulder point to the other.
- Back (H): from the base of the neck to the waistline.
Weight is in kilograms and height is your full height in centimetres.
Measuring points from OMP’s guide, shown on front and back outlines. A to D are circumferences measured around the body; the short lines mark their position. The drawing is not to scale.
Scroll across the diagram for both views.
Garreth would write the readings down before opening the chart, so the numbers come from the tape. Check the inside leg too. A size that looks suitable across the shoulders can still be too short through the body and legs.

The OMP First S Race Suit
The First-S, part family IA0-1828-E01, is a two-layer suit homologated to FIA 8856-2018. OMP describes a soft knitted inner fabric, flat seams, floating arms with elastic bellows and a knitted stretch insert across the back.
Our listing offers black, blue, red, silver and yellow options in sizes 44 to 64. Check the selected colour’s photograph on the product page alongside the size you need. Cameron would still check movement and comfort in a driving position when trying the suit.

When the chart does not fit you
If your chest, waist and inside leg point to different sizes, send us the complete readings. Cameron would look at where the fit changes before suggesting a different size or cut. Simply moving up for extra leg length also increases the room elsewhere.
Our guide to race-suit alterations explains what to check before modifying a suit. You can also read about custom race-suit options, choosing an FIA race suit and fire-resistant underwear. Browse the wider racing-suit range if you are comparing cuts.
Common questions
Will a First-S fit someone who is 180cm and 85kg?
Size 54 is a starting suggestion, while 52 also includes that height and weight; compare the full body-measurement row before ordering.
What if I am between two sizes?
OMP advises choosing the larger size when you fall between two sizes.
Should I measure over racing underwear?
Yes, OMP’s measuring guide advises taking suit measurements with your racing underwear on.
Are the figures the size of the finished suit?
They are body measurements, so compare them with your own readings.
Height and weight suggest different sizes. Which do I choose?
Compare chest, waist, hips, inside leg and the remaining measurements together, and ask us to check the readings if they point to different sizes.
Can I choose different suit, boot and glove sizes?
Check the actual options on the bundle: the medium First-S set lists 52–58 suits, EU 42–45 boot options and M gloves. Ask us about another combination if those do not match your measurements.
Can you check my size before I order?
Send your height, weight and body measurements by email or chat so we can compare them with OMP’s chart.
What we would buy
Garreth
Garreth’s top tip
I'd start by checking 54 for this question. I'd keep 52 beside it because the height and weight bands overlap. The body measurements and a try-on would settle which one to order.
Cameron
Cameron’s fitting view
Show me chest, waist, hips and inside leg together, then the arm, shoulder, thigh and back measurements. A 54 row has 107–111cm chest and 80–82cm inside leg, but every part of the fit needs to work for you.
