Your total height from the floor to the very top of your head, measured without shoes. This is the foundation measurement that helps scale every other measurement for your garment.

1. Remove your shoes and stand on a hard, flat floor with your back against a wall.
2. Stand up straight — heels touching the wall, shoulders back, eyes looking straight ahead (not up or down).
3. Have someone place a flat, rigid object (a hardcover book or ruler) on top of your head so it touches the wall.
4. Mark the wall lightly with a pencil at the bottom edge of the book.
5. Step away and measure from the floor straight up to the pencil mark.

Your current body weight. This isn't used for sizing directly, but it helps your tailor understand body density and predict how fabric will drape and where ease is needed.

1. Use a bathroom scale on a hard, flat surface (not carpet — it can give inaccurate readings).
2. Weigh yourself wearing lightweight clothing — similar to what you'd wear under the garment.
3. For the most consistent result, weigh yourself at the same time of day (morning is best, after using the restroom).

Your approximate age. Bodies change shape over time — shoulders may round, posture may shift, and the torso may shorten. Knowing your age helps your tailor anticipate these tendencies and make small fit adjustments.

1. Simply enter your age in years. No measuring needed!

How much your shoulders angle downward from your neck to your arms. Imagine a line from the base of your neck to the tip of your shoulder — is it angled steeply down, roughly level, or nearly horizontal? This determines how the jacket shoulder seam is shaped.

1. Stand naturally in front of a mirror wearing a fitted T-shirt (not a puffy sweater — you need to see your actual shoulder line).
2. Let your arms hang relaxed at your sides. Don't shrug or pull your shoulders back.
3. Look at the line from where your neck meets your shoulder, out to the bony tip of your shoulder (the point where your arm begins).
4. Sloped = the line angles noticeably downward. Normal = a gentle, slight slope. Square = your shoulders are nearly horizontal / level.

Your midsection profile when viewed from the side. This affects how the jacket front panels are cut — a prominent stomach needs extra fabric length in the front so the jacket doesn't ride up or pull open.

1. Stand naturally in front of a full-length mirror and turn to see your side profile (or have someone take a photo from the side).
2. Don't suck in your stomach — stand the way you normally do when you're relaxed.
3. Look at the area between your chest and your belt line. Is your stomach flat and vertical? Does it have a gentle curve? Or does it extend noticeably forward?
4. Flat = your stomach is roughly in line with your chest. Average = a gentle curve. Prominent = your stomach extends noticeably beyond your chest line.

Your natural standing posture viewed from the side. This tells the tailor whether to add more fabric in the front or back of the jacket so it hangs evenly and doesn't bunch up.

1. Stand the way you normally do — don't try to "stand up straight" or correct your posture.
2. Have someone look at you from the side, or take a side-profile photo.
3. Forward Lean: your head and shoulders tend to come forward of your hips (common if you sit at a desk all day).
4. Normal / Upright: your ears, shoulders, and hips are roughly stacked vertically.
5. Backward Lean: your upper body leans slightly behind your hips (less common, sometimes called a "military posture").

How close to your body you want the finished garment to be. This controls the amount of "ease" — extra room — the tailor adds beyond your actual body measurements.

1. Think about the clothing you already own and feel most comfortable in.
2. Slim: the garment follows your body closely with minimal extra room. You can see your body shape clearly. Great for a modern, sharp look.
3. Standard: shaped to your body but with enough room to move, sit, and reach comfortably without pulling. The most versatile choice.
4. Relaxed: generous room throughout. The fabric drapes loosely. Ideal if you prioritize comfort or prefer a classic, roomy silhouette.

The circumference around the base of your neck — right where a dress shirt collar sits. This measurement determines your collar size and ensures the finished collar is snug enough to look sharp but loose enough to be comfortable all day.

1. Stand in front of a mirror and look straight ahead.
2. Find the base of your neck: it's the point where your neck meets your shoulders. On the front, this is roughly where the top of your collarbone (the V-shaped notch) is. On the back, it's the large bony bump you can feel when you tilt your head forward.
3. Wrap the measuring tape around your neck at this level, keeping it flat — not twisted.
4. Slip one finger between the tape and your neck. This ensures the collar won't feel like it's choking you.
5. Read the number where the tape overlaps. That's your neck measurement.

The distance across your upper back from one shoulder tip to the other. The "shoulder tip" is the bony point at the very edge of each shoulder — the spot where your arm bone connects to your shoulder (you can feel it if you press on the top of your shoulder and move outward until you hit a bony bump). This sets where the sleeve seam sits on your garment.

1. You will need a helper for this one — it's nearly impossible to measure accurately on your own.
2. Stand naturally with your arms relaxed at your sides. Don't pull your shoulders back or puff your chest out.
3. Your helper should find the bony tip of one shoulder (the point where the top of your arm meets the shoulder — press around until you feel a hard bony edge).
4. Place one end of the tape on that bony tip, then run the tape across your upper back (following the natural curve of your back, not a straight line) to the same bony tip on the other shoulder.
5. The tape should cross over the large bony bump at the base of your neck (the "7th vertebra" bump you feel when you tilt your head forward).

The circumference around the fullest part of your chest. For most men this is at nipple level; for most women it's across the bust. This is the single most important measurement for jackets, shirts, and coats — it determines your primary garment size.

1. Wear a thin T-shirt or no shirt. Don't measure over a thick sweater or jacket.
2. Stand naturally with your arms relaxed at your sides (not raised — raising your arms changes the measurement).
3. Wrap the tape around the fullest part of your chest. In the front, the tape should cross the widest point. In the back, it should run across your shoulder blades.
4. Make sure the tape is level all the way around — not dipping lower in the back. Use a mirror or have someone check.
5. Breathe out normally (don't hold a deep breath or exhale completely) and read the number.

The circumference around your midsection at its widest point — typically at or just below your navel (belly button). This is NOT where your belt sits (that's the "pants waist" measured later). Your natural waist is used for jacket buttoning points and front panel shaping.

1. Stand naturally and relaxed — do NOT suck in your stomach. Breathe normally.
2. Find your navel (belly button). Wrap the tape around your midsection at that level, or at the widest point of your stomach if it's slightly above or below your navel.
3. Make sure the tape is level all the way around — use a mirror to check the back isn't sagging or riding up.
4. The tape should be snug against your body but not digging in. You should be able to slip a finger under it.
5. Breathe out gently and read the number.

The circumference around your body at the level where a jacket hem falls — typically 7–8 inches (18–20 cm) below your natural waist. This is where the bottom of a sport coat or blazer ends, and it ensures the jacket doesn't flare out or cling at the bottom.

1. Stand naturally with your feet about hip-width apart.
2. Find the right level: if you own a jacket, put it on and note where the hem falls. If not, place your hand on your hip bone — the measurement level is roughly at the top of your hip bones.
3. Wrap the tape around your body at that level — it will cross over your hip bones on the sides and your seat in the back.
4. Keep the tape level and snug but not pulling.
5. Read the measurement.

The length from the center of the back of your neck, across your shoulder, down the outside of your arm to your wrist bone. This determines how long your jacket or shirt sleeves will be. Getting this right ensures about ½ inch of shirt cuff peeks out below the jacket sleeve — the classic look.

1. You will need a helper for this measurement.
2. Stand naturally and bend your arm slightly at the elbow — as if your hand is resting on your hip. A slight bend is important because sleeves need to be long enough for when you move.
3. Your helper places one end of the tape at the large bony bump on the back of your neck (you can feel it when you tilt your head forward — it's the same bump used in the shoulder measurement).
4. Run the tape across the top of your shoulder to the bony shoulder tip (the same point used in the shoulder width measurement).
5. Continue down the outside of your arm, following the natural line over the elbow bend, all the way down to your wrist bone — the protruding bony bump on the outside of your wrist.

The circumference around the thickest part of your upper arm — usually halfway between your shoulder tip and your elbow. This ensures the sleeve is roomy enough through the upper arm so it doesn't pull or restrict movement when you bend your arm.

1. Let your arm hang naturally at your side — do NOT flex or tense your muscle.
2. Find the midpoint between your shoulder tip (bony bump at the edge of your shoulder) and the point of your elbow.
3. Wrap the tape around your arm at that midpoint. The tape should be flat, level, and snug — but not squeezing your skin.
4. Read the measurement.
5. Measure your dominant arm (right arm if right-handed) — it is usually slightly larger.

The circumference around your wrist, just above the wrist bones (the two protruding bumps on either side of your wrist). This determines your shirt cuff size and how the jacket sleeve finishes.

1. Remove any watch, bracelet, or jewelry from your wrist.
2. Find your wrist bones — the two bony bumps on the inner and outer sides of your wrist, right where your hand begins.
3. Wrap the tape around your wrist just above (toward the elbow side of) those bony bumps.
4. Pull the tape snug against the skin — the wrist has very little soft tissue, so you want it firm but not cutting in.
5. Read the measurement.

How long the jacket is from the base of your neck down your spine to the hem. A well-proportioned jacket should cover your seat (backside) completely and end right about where your curled fingers fall when your arms hang naturally — roughly dividing your body in half from collar to floor.

1. You will need a helper for this measurement.
2. Stand up straight with your arms relaxed at your sides.
3. Your helper places one end of the tape at the large bony bump on the back of your neck (the same bump from the sleeve measurement — tilt your head forward to find it).
4. Run the tape straight down your spine to the point where you want the jacket to end. For a classic fit, this is roughly where your thumb knuckle is when your arms hang naturally.
5. The tape should follow your spine, not float away from your back.

The circumference around your body where you actually wear your trousers — which is NOT necessarily your natural waist. Some people wear trousers at their natural waist (at or above the navel), others wear them lower on the hips. Measure where YOUR pants actually sit, because that's where the waistband will be built.

1. Put on a pair of trousers (or pants) that fit you well and sit at the height you prefer.
2. Note where the waistband sits on your body — this is your trouser-waist level.
3. Remove the trousers (or move them aside) and wrap the measuring tape around your body at that exact same level.
4. The tape should be snug but you should be able to slip one finger between the tape and your body.
5. Breathe out normally and read the measurement.

The circumference around the absolute widest part of your hips and seat (buttocks). This is usually 7–9 inches (18–23 cm) below your waistband. If trousers are too tight here, they'll pull and wrinkle across the back; too loose and they'll sag.

1. Stand with your feet together and your weight evenly distributed on both feet.
2. Find the widest point: it's usually across the most prominent part of your buttocks, roughly at mid-hip level. If you're unsure, wrap the tape around at a few different heights and note the largest number — that's the spot.
3. Wrap the tape around at that widest level, making sure it stays level (parallel to the floor) all the way around.
4. The tape should be flat against your body — snug but not compressing. Don't let it slip down in the front.
5. Read the measurement.

The total length from the front center of your waistband, down through your legs, and up to the back center of your waistband — like a loop under the crotch. This combined measurement determines both the front rise (how high the trousers sit in front) and back rise (how high they sit in back). Get this wrong and the trousers will either wedge or sag.

1. Put on a pair of trousers that fit well at the waist.
2. Stand naturally with feet about shoulder-width apart.
3. Place the end of the tape at the center front of your waistband — right at the button or closure.
4. Run the tape straight down from the front waistband, between your legs (through the crotch area), and straight up the back to the center of the back waistband.
5. The tape should follow the seam line of well-fitting trousers. Keep it snug against your body but comfortable — don't pull it tight.

The circumference around the thickest part of your upper thigh, right at the top of the leg where it meets the crotch. This measurement ensures the trouser legs have enough room through the thigh so they don't bind when you walk, sit, or climb stairs.

1. Stand upright with your weight evenly on both feet, legs slightly apart (not pressed together).
2. Find the thickest part of your upper thigh — this is usually right at the very top of your leg, about 1 inch (2–3 cm) below where your leg meets your crotch.
3. Wrap the tape around your thigh at that point, keeping it level (parallel to the floor).
4. The tape should be snug but not squeezing — you should be able to slide a finger under it.
5. Measure your dominant leg (right if right-handed) — it's typically slightly larger.

The circumference around the middle of your knee. This measurement helps the tailor shape the taper of the trouser leg from the thigh down to the hem — it's the "midpoint" that defines the trouser silhouette.

1. Stand straight with your legs relaxed and slightly apart — do NOT bend your knee.
2. Find the center of your kneecap by placing your finger on the middle of the front of your knee.
3. Wrap the tape around your leg at that level, keeping it level all the way around.
4. Keep the tape snug but comfortable — the same tension as the thigh measurement.
5. Read the measurement.

The length from the top of your waistband straight down the outside of your leg to where you want the trouser hem to end — usually the top of your shoe or the point where the trouser just touches ("breaks on") your shoe. This is called the "outseam" and it determines how long or short your trousers will be.

1. Put on the shoes you plan to wear most often with these trousers.
2. Stand naturally on a flat surface with your feet about hip-width apart.
3. Have your helper place one end of the tape at the top of your natural waistband (where you normally wear your trousers) on the outside of your hip.
4. Run the tape straight down the outside of your leg to the desired hem length. For a classic "medium break," the tape should reach the point where the front of the trouser would just touch the top of your shoe and create a small fold.
5. If you prefer no break (modern/slim): measure to the top of the shoe. Half break: to where the fabric just barely touches the shoe. Full break: add ½–1 inch past the shoe top.
