Here’s the simple version: hollow to floor is the distance from the small hollow at the base of your throat (between your collarbones) straight down to the floor.
Stand straight, barefoot, and have a helper place a soft tape at your hollow and measure straight down to the floor; if you’ll wear heels, add your heel height (minus any platform) to get your hollow-to-hem ordering length.
Hollow to floor: the fast answer and how to measure it
Because many brands build size and length around this number, getting it right saves time, stress, and alteration costs. Use these two-minute steps for a number you can trust.
- Wear the right layers: go barefoot and wear the bra or cups you plan to use. Skip bulky robes or sweaters that can push the tape off the hollow.
- Stand tall and look ahead: feet together, posture relaxed but upright, shoulders neutral.
- Find the “hollow”: the little dip between your collarbones at the base of your throat.
- Place the zero end of a soft, flexible dressmaker tape at the hollow. Keep the tape vertical, brushing the center front of your body.
- Let the tape fall straight to the floor, grazing the front of the body, without curving over the bust or following contours.
- Read where the tape touches the floor. That’s your barefoot hollow-to-floor in inches (and record centimeters too).
Add-ons calculator (quick rules of thumb):
- Planned heel height: add the heel height in inches.
- Platform under the ball of the foot: subtract that height from the heel height before adding. Net heel add = heel height − platform height.
- Petticoat or hoop: full underlayers can lift skirts 0.25–0.75 in; add back 0.5 in if your skirt is very full and you’ll wear a stiff petticoat.
- Floor skimming preference: add 0–0.5 in if you like a soft “kiss the floor” look, subtract 0.25–0.5 in if you prefer the hem slightly off the ground.
Sanity check (avoid a bad number): your barefoot hollow-to-floor will usually be 8–10 inches less than your total height because it starts from your neck, not the top of your head. If your number is only 2–3 inches less than your height or more than a foot shorter, re-measure with a helper and a straight tape.
Common mistakes to avoid:
- Measuring over the curve of the bust. The tape should hang straight down, not contour.
- Looking down or slouching. Keep your gaze forward so posture stays natural.
- Measuring in shoes when the brand asks for barefoot hollow-to-floor. Follow the brand’s instruction precisely.
- Forgetting to account for platforms, which change the net heel add.
- Pulling the tape tight so it bows off the body. Let it skim, not stretch.
Hollow-to-floor vs hollow-to-hem vs other dress measurements
Brands don’t always use the same term. Here’s how to decode requests so you provide the right number the first time.
| Term | What it measures (start/end) | Includes shoes? | Use for | Notes/pitfalls |
|---|---|---|---|---|
| Hollow to floor | From throat hollow to floor | Usually barefoot | Bridal and formal gowns that are floor length | Measure straight down; add heel height separately if the brand instructs |
| Hollow to hem | From throat hollow to finished hem | Often includes heel add | Custom orders where you specify finished length | Ask if they want barefoot H2F plus heel add, or one combined “to hem” number |
| Shoulder to hem | High shoulder point to hem | Varies | High-neck, illusion or asymmetrical bodices | Useful when the neckline is far above the hollow |
| Waist to hem | Natural waist to finished hem | Varies | Tea-length, ankle, high-low, and separates | Best when a dress isn’t intended to touch the floor |
| Back length with train | Center back waist to hem | N/A | Gowns with trains | Hem and train are different; train length is its own design choice |
When do brands ask for each? Floor-length bridal designers often publish a standard hollow-to-floor chart and may offer custom hollow-to-hem if your height or heel plan sits outside the standard. For non-floor lengths (tea, midi, mini) and jumpsuits, you’ll commonly see shoulder-to-hem or waist-to-hem requests instead.
Shoes, underlayers, and style details that change your number
Shoes first. Heels make the biggest difference, and platforms change the math.
- Heels with no platform: add the heel height in full. A 3 in heel = +3 in to your hollow-to-floor when ordering a finished hollow-to-hem.
- Platform heels: subtract the platform height from the heel, then add the net. A 4 in heel with a 1 in platform = +3 in net.
- Flats on dance floor: if you’ll switch to flats later, consider ordering the gown to skim the floor in heels so it sits slightly longer when you change shoes, rather than risk a too-short front when photographed early.
Underlayers matter next. Full petticoats and hoops can lift skirts noticeably:
- Slim or sheath skirts: little to no lift. No extra add needed.
- A-line and ball gowns with medium petticoats: +0.25–0.5 in consideration helps you avoid an unexpected hover.
- Very stiff petticoats or hoops: plan +0.5–0.75 in, or measure hollow-to-floor while wearing the hoop so you capture the true drape.
Style details to consider:
- Trains: train length does not change your hollow-to-floor. The train extends behind the standard hem and is a separate design measurement.
- Lace or scalloped hems: delicate edges are harder to shorten cleanly. If you are between lengths, consider ordering the longer option and budgeting for a careful hem from an experienced bridal tailor.
- High necklines and illusion bodices: if the neckline sits well above the hollow, some brands prefer shoulder-to-hem instead of hollow-based measurements.
Standard lengths and brand differences: how to order with confidence
Many bridal brands work from standard “floor length” blocks and publish charts that correlate hollow-to-floor to an assumed height. Common finished lengths range around 58–61 inches, but the reference height (with or without shoes) varies by label. Always read the chart footnotes.
How to read a length chart:
- Locate your barefoot hollow-to-floor and your planned heel height. Some charts list barefoot hollow-to-floor with a separate column that shows what heel height range that length supports.
- Check the assumed model height. A few brands assume a wearer of roughly 5 ft 7–9 in with heels for their standard sample length, while others assume a barefoot reference. That affects whether you add heel height yourself or pick a pre-added column.
- Look for “extra length” options. Many offer +1–4 inches (sometimes more) to serve tall wearers or higher heels.
If you’re petite: You’ll often fit standard hollow-to-floor but will need a hem. Structured skirts with lace borders can be trickier; you may prefer ordering custom hollow-to-hem if available to reduce complex hemming. Our primer on fit and silhouette can help you choose construction that’s easier to alter: The ultimate wedding dress up guide: silhouettes, fit and style.
If you’re tall or planning higher heels: Choose extra length when offered. It’s easier to shorten than to add length later. If extra length isn’t available, ask the boutique whether the designer allows custom hollow-to-hem, or plan for an experienced tailor to face or horsehair the hem for a crisp finish.

When hollow to floor is not the right measurement
Hollow-based measurements shine for floor-length gowns that start at or near the throat hollow. They mislead when the design line is elsewhere.
- Tea-length, midi, ankle, or calf hemlines: use waist-to-hem or shoulder-to-hem. These styles are defined by where the hem hits the leg, not by the floor.
- High-low hems: provide both front waist-to-hem and back (or total) length as the brand requests. Hollow-based numbers won’t describe the angle well.
- Jumpsuits and pants: inseam, outseam, and waist-to-floor are the right calls, often with heel height specified.
- Very high or low necklines and one-shoulder/illusion tops: shoulder-to-hem will map the actual pattern piece better than hollow-based measures.
Special notes:
- Illusion necklines with sheer tulle above the hollow: if a brand still requests hollow to floor, measure as usual but confirm whether they will internally convert to shoulder-to-hem.
- Asymmetrical hems or layered tulle skirts: supply any additional lengths the brand asks for and be prepared for a skilled tailor to fine-tune the finish once you have the piece in hand.
Alterations vs ordering extra length: cost, time, and fit
Hemming timelines and costs vary by city, fabric, and complexity, but these ballpark ranges can help you plan.
- Straight machine hem (chiffon, georgette, crepe): often about $40–$120.
- Horsehair braid hem finishing: about $60–$180 depending on width and layers.
- Multiple skirt layers (tulle over satin lining): $120–$300+ because each layer needs separate handling.
- Lace border or scalloped edge: hand work can push hems to $150–$400+ based on motif placement.
Timelines:
- Simple hems: 1–3 weeks with one fitting.
- Layered or lace hems: 3–8 weeks with two to three fittings.
- Peak seasons: spring and early summer can extend timelines; book earlier.
When to order extra length instead of hemming:
- You’re 5 ft 9 in and planning 3–4 in heels, or your barefoot hollow-to-floor is already near the brand’s longest standard length.
- The design has a significant lace border you’d like to preserve.
- Your venue has textured ground (brick, grass) and you prefer a slight forward “break” rather than a high hem.
When hemming is the smarter play:
- You’re between sizes but within 1–2 inches of standard length and wearing modest heels.
- Your dress has a clean edge that shortens well, like crepe or satin without a border.
- You want a specific off-floor clearance to move easily all night.
Plan your path:
- Measurement day: capture barefoot hollow-to-floor twice, note heel and platform, and log your desired hem behavior (skim vs off-floor).
- Order week: pick standard or extra length per the chart and your add-ons calculator.
- Try-on day: bring the exact shoes and underlayers to the first fitting so your tailor pins the true final length.

FAQs about hollow to floor
How do I take a hollow to floor measurement? Stand barefoot with natural posture. Have a helper place a soft tape at the hollow between your collarbones and let it fall straight to the floor. Record that barefoot number, then add your net heel height if the brand asks for a finished hollow-to-hem length.
What is the difference between hollow to floor and hollow to hem? Hollow to floor ends at the floor and is usually taken barefoot. Hollow to hem ends at the finished hem once shoes and preferences are considered. Some brands ask for barefoot hollow-to-floor and then request your heel height separately; others ask for a single finished hollow-to-hem value.
Should I add heel height to my hollow-to-floor measurement, and how much? Only add heel height if the brand asks for a finished hollow-to-hem. Add your heel height minus any platform under the ball of your foot. Example: a 3.5 in heel with a 0.5 in platform equals a +3.0 in net add.
How long should a floor-length dress be? Many brides like a front hem that skims the floor in their shoes, with the back slightly longer or train-defined. For easy movement on textured ground, order the front hem about 0.25–0.5 in off the floor.
Can I measure hollow to floor by myself? You can, but accuracy drops. It’s hard to keep the tape flush and vertical without bending. Ask a helper. If you must go solo, tape the zero point at your hollow, look straight ahead, and photograph the floor reading to double-check.
What if I’m 5′2″ or 5′7″ — do I follow a chart or my measurement? Use your own measurement first and let the chart confirm your choice. If your barefoot hollow-to-floor plus your planned heel add doesn’t match a standard length, choose extra length or plan an alteration. Charts are guides; your number is the truth.
Does a train change the hollow-to-floor measurement? No. Train length is added behind the standard hem and is a separate design measurement. Your front hollow-to-hem is still set by your height, shoes, and preferences.
What if my measurement doesn’t match my height “by the book”? Re-measure. The barefoot hollow-to-floor is usually 8–10 in shorter than your total height. If you’re far outside that band, posture, tape angle, or floor reading may be off.
Do petticoats and hoops matter? Yes. Full underlayers can lift skirts 0.25–0.75 in. If you will wear a hoop or stiff petticoat, add about 0.5 in to your finished length or measure while wearing the underlayer.
Where can I learn more about picking styles that hem well? Start with construction and silhouette basics here: The ultimate wedding dress up guide: silhouettes, fit and style, then pair length choices with styling ideas from Wedding Dress Styling Tips: Build Your Bridal Look That Lasts.
Dial in hollow to floor once, and every other decision — chart, custom length, or alteration — becomes simpler. Capture the number barefoot with a helper, add a careful heel calculation, and confirm against the brand’s chart. After that, you’re free to focus on the fun parts, like personal touches and accessories that make the look yours.
