If you want a precise sizing, it's important you spend 2 minutes in measuring your body properly. Please measure your body precisely, if possible without any clothes on.

How to measure your shoulders

Think of a line going from your armpit straight upwards to your shoulder. Measure between those two points and hold the tape measure straight. Measure between the points of your shoulders, where a sleeve seam of a normal t-shirt would be.

How to measure your chest

Wrap the tape measure under your armpits, around the fullest part of your chest. The tape measure should be snug. Not so tight that it constricts breathing, but not so loose that the tape measure slides down. Don’t puff out or flex your chest. Just stand normally.

How to measure your waist

Measure around your waist at about navel level, put a finger between your body and the tape measure to ensure maximum comfort.

How to measure your Hips

Measure the circumference of your hips. Start at one hip and wrap the tape measure around your rear, around the other hip, and back to where you started. Make sure the tape is over the largest part of your buttocks. Because making sure the tape is level back there can be hard, try to do it in front of a mirror.

How to measure your Thigh

Measure the circumference of the fullest part of your thigh. Wrap the tape measure around your thigh from front to back and then around to the front. You may be tempted to cheat by lowering the tape measure a few inches, but then you won’t get an accurate measurement.

How to measure your sleeve

Simply start the measuring tape from your shoulder and measure till the end of the wrist, just before the palm.

How to measure your inseam

The inseam measurement is taken from the underside of the crotch (or top inseam point) to the bottom side of the ankle (bottom inseam point).

The following table shows precise measures of the final product.

Size guide — how the system works

This page explains how Opera Campi suggests sizes. There are two methods: one based on body measurements in cm, and one based on weight and height ratio. The measurement method is more accurate and takes priority when the customer knows their measurements. The weight/height method is used when only weight and height are available.

Method 1 — Body measurements

This table shows the garment measurements (in cm) for each size. These are the measurements of the finished garment, not the body. To find the right size, take the customer's body measurement, add the allowance percentage shown in the allowance table below, and find the first size whose garment measurement equals or exceeds that value.

Formula: body measurement × (1 + allowance) ≤ garment measurement → that is the correct size.

Example: chest = 92 cm, allowance = 7% → 92 × 1.07 = 98.44 cm → first size with chest ≥ 98.44 is S (100 cm) → suggest S.

Size	Chest (cm)	Shoulders (cm)	Waist (cm)	Hips (cm)	Thigh (cm)
XXS	92	39	72	93	55
XS	96	40	76	97	57
S	100	41	80	101	59
M	104	42	84	105	61
L	108	43	88	109	63
XL	112	44	92	113	65
XXL	116	45	96	117	67
XXXL	120	46	100	120	69

Allowance table

Always add the allowance percentage to the customer's body measurement before comparing with the table above. The allowance accounts for ease of movement and the garment's intended fit. Shoulders have a very small allowance (1%) because they are structural. Waist has a negative allowance (-1%) meaning the garment is slightly fitted at the waist.

Measurement	Male allowance	Female allowance
Chest	7% (0.07)	7% (0.07)
Shoulders	1% (0.01)	1% (0.01)
Waist	-1% (-0.01)	-1% (-0.01)
Hips	5.5% (0.055)	5.5% (0.055)
Thigh	5% (0.05)	5% (0.05)

When multiple measurements are provided, always take the largest suggested size across all of them. The size is determined by the most constraining measurement.

Example: chest suggests M, waist suggests L → suggest L.

Method 2 — Weight and height ratio

When the customer does not know their body measurements in cm, use weight (kg) divided by height (cm) to calculate a ratio. Compare the ratio with the threshold table below to find the suggested size. Use the Male table for male products, the Female table for female products. For unisex products, ask the customer which fit they prefer before choosing the table.

Formula: ratio = weight ÷ height. Example: 70 kg ÷ 180 cm = 0.389 → M (male).

Ratio thresholds — Male

XXXL	> 0.625	110+ kg / 177 cm	P95 from real orders ✓

S	0.331 – 0.390	53–65 kg / 167 cm	P95 from real orders ✓
M	0.390 – 0.430	60–70 kg / 169 cm	P95 from real orders ✓
L	0.430 – 0.468	68–75 kg / 170 cm	Sparse data, interpolated
XL	0.468 – 0.526	75–95 kg / 174 cm	P95 from real orders ✓

Rules and edge cases

Method priority: if the customer provides body measurements in cm, always use Method 1. The weight/height ratio is a fallback only.

S/M borderline (male): for a 180 cm man, the S/M boundary is at approximately 69–70 kg. A difference of 1 kg changes the size. If the customer is unsure, suggest M for a relaxed fit and S for a closer fit.

Products starting from S: if the product does not carry XXXS, XXS or XS, the system skips those thresholds and assigns the smallest available size. A customer with ratio 0.320 on an S-to-XXL product will receive S.

Unisex products: always ask whether the customer wants a male or female fit before choosing the ratio table. The same person will receive different size suggestions depending on the answer.

Made to measure: if the customer's ratio is below 0.265 (male) or 0.255 (female), or if their body measurements fall significantly outside the table range, suggest the made-to-measure option rather than forcing an extreme size.

Material and fit: knitwear (filato) has natural stretch and is more forgiving at borderline sizes. Woven fabric (tessuto) follows the thresholds more strictly. When in doubt on a woven garment, suggest the larger size.

Multiple measurements conflict: when different body measurements point to different sizes, always go with the largest suggested size. Never average them.

Further assistance: if you are doubtful, you can suggest the user to write at casa@operacampi.com or to chat through the other chat in the bottom right of the webpage to talk directly with one of the team of Opera Campi

How to respond to size questions

If the customer provides weight and height: calculate the ratio (weight ÷ height), use the correct table based on sex or product type, state the suggested size.

If the customer provides body measurements in cm: apply the allowance, compare with the size table, and return the first size that fits all measurements. Always state which measurement was the deciding factor.

If the customer provides neither: ask for at least weight and height. Do not guess a size based on general descriptions like "average build" or "medium frame".

If the customer is between two sizes: ask whether they prefer a relaxed or close fit, then recommend accordingly. Never leave the customer without a clear recommendation.

If the customer gives the measurements of another garment, you don't need to add margin. The margin needs to be added only to body measures.
