What Is Hollow to Hem? Definition, How to Measure It & Why It Matters

Updated October 2026 by the MsDressly editorial team.

What hollow to hem means

Hollow to hem measures the distance from the hollow of your neck to the hem of a garment. The "hollow" is the natural indentation at the front base of your throat, right where your collarbones meet. The "hem" is the finished bottom edge of a dress or skirt — floor length, ankle length, or wherever the design ends.

Unlike inseam or outseam measurements for pants, hollow to hem is designed for dresses. It captures both your torso length and your leg length in one vertical line, which is exactly what a dressmaker needs to predict where a hem will land on your body.

Why this measurement matters

A size chart tells a brand your width — bust, waist, hips. It tells them nothing about your length. Two women can both wear a size 8 and differ by six inches in hollow to hem, which is the difference between a gown that kisses the floor and one that pools in puddles.

This is especially critical for:

• Floor-length and formal gowns, where an inaccurate measurement leads to expensive alterations or a hem that drags.
• Petite shoppers ordering standard-length maxi dresses, since standard patterns are graded for taller average heights.
• High-low and midi hemlines, where a few inches changes the intended proportion of the design entirely.

How to measure hollow to hem

You need a soft measuring tape, flat shoes (or the exact heel height you'll wear with the dress), and ideally a friend to help.

• Stand straight with your shoulders relaxed and your feet together.
• Find the hollow: the dip at the base of your neck, between your collarbones.
• Place the end of the tape in the hollow and run it straight down the front of your body, following your natural shape — over the bust, along the torso, and down the legs.
• Stop at your desired hem point: the floor for a full-length gown, the ankle for a midi, the top of your foot for a maxi with heels.
• Keep the tape taut but not tight, and record the number in inches.

Wear the undergarments and shoes you plan to wear with the final outfit — both change where the hem falls. If you're between sizes on length, round up; shortening a hem is far easier than adding fabric.

Hollow to hem vs. hollow to floor

These two terms are often used interchangeably, but there's a subtle distinction worth knowing. Hollow to floor is strictly the measurement to the floor itself, barefoot or in the shoes you'll wear. Hollow to hem measures to the intended hem of a specific garment — which may fall above the floor, as with midi, tea-length, or high-low designs.

When a bridal or formalwear size chart asks for "hollow to hem," it usually means "hollow to floor in your event shoes." For casual and midi dresses, read the chart's instructions carefully to see which hem point they expect. If in doubt, measure to the floor and note the difference.

How it differs from other measurements

Shoppers often confuse hollow to hem with these related numbers:

• Height (full body): total stature from crown to floor. Hollow to hem starts lower and runs down the front, so it accounts for torso proportions height alone misses.
• Waist to hem: used for skirts only; it starts at the natural waistline, not the neck hollow.
• Back length / nape to hem: measured from the bony bump at the back of the neck. Back lengths run differently than front lengths because of the spine, which is why hollow (front) to hem is the standard for dresses.
• Inseam: a pants-only measurement from crotch to ankle — never used for dresses.

Typical hollow to hem ranges

Exact numbers vary by body, but most standard women's patterns are drafted around a hollow to hem of roughly 58–61 inches for floor-length gowns. Petite sizes typically run about 2–3 inches shorter, while tall or plus-length patterns run longer. A midi dress usually needs a hollow to hem of around 42–48 inches, depending on your height and where you want it to hit.

Treat any chart as a starting point, not gospel: always compare the brand's listed "model wears size X, hollow to hem Y" notes, if provided, against your own number.

Common measuring mistakes

• Measuring in bare feet when you'll wear heels — the number one error. Always measure in your event shoes.
• Tilting the head down to look at the tape, which shifts the hollow point. Keep your chin level.
• Measuring over thick clothing — a bulky sweater adds visible inches. Measure over a fitted tank or thin dress.
• Letting the tape drift off the center front line. The tape must travel straight down your midline, not around curves diagonally.
• Guessing instead of asking for help — solo measurements almost always read short because you can't hold the tape's top end steady at your own neck hollow.

How to shop using your hollow to hem number

Before ordering any long dress, find the garment's listed length (often "length from shoulder" or "length from high point of shoulder") and compare it to your measurement. If the product page only gives a hollow-to-hem range per size, choose the size whose range brackets your number.

If you run shorter than standard lengths, browse cuts designed with petite proportions in mind — the maxi dresses for petite women collection is a smart place to start. Shorter hemlines with intentional shaping, like a ribbed asymmetrical-hem top or an off-shoulder jumpsuit with a drawstring frill hem, are also forgiving because their hemlines are meant to vary by wearer.
