Mondor uses Canadian age-based sizing, which can feel different from the numbered gymnastics sizes commonly used in Europe. For the best fit, use the body measurements rather than choosing by age alone. For leotards, girth is particularly important because it reflects the full length of the torso.
From our fitting experience, Mondor's 8–10 generally feels closest to approximately a The Zone size 28. We use this only as a familiar reference for customers - it is not an official brand-to-brand size conversion.
Mondor Girls' Gymnastics Size Chart
Compare bust, waist, hips and girth to find the best starting size. The age label is a guide only.
| Mondor Size | Dance World Reference | Bust | Waist | Hips | Girth |
|---|---|---|---|---|---|
| 6X–7 | ≈ The Zone 26 | 60.5–66 cm 24–26" | 50.5–53 cm 20–21" | 66–71 cm 26–28" | 106.5–114 cm 42–45" |
| 8–10 | ≈ The Zone 28 | 66–71 cm 26–28" | 53–55.5 cm 21–22" | 71–76 cm 28–30" | 116.5–124 cm 46–49" |
| 10–12 | ≈ The Zone 30 | 71–76 cm 28–30" | 55.5–58 cm 22–23" | 76–81 cm 30–32" | 127–132 cm 50–52" |
| 12–14 | ≈ The Zone 32 | 73.5–81 cm 29–32" | 58–60.5 cm 23–24" | 78.5–86 cm 31–34" | 132–139.5 cm 52–55" |
Mondor Women's Size Chart
Adult Mondor dancewear sizing uses S, M, L and XL. Compare bust, waist, hips and girth rather than converting directly from everyday clothing size.
| Size | Bust | Waist | Hips | Girth |
|---|---|---|---|---|
| S | 78.5–86 cm 31–34" | 60.5–68.5 cm 24–27" | 83.5–91 cm 33–36" | 142–149.5 cm 56–59" |
| M | 83.5–91 cm 33–36" | 66–73.5 cm 26–29" | 91–99 cm 36–39" | 149.5–157 cm 59–62" |
| L | 88.5–96.5 cm 35–38" | 73.5–81 cm 29–32" | 99–106.5 cm 39–42" | 157–165 cm 62–65" |
| XL | 99–106.5 cm 39–42" | 81–88.5 cm 32–35" | 104–111.5 cm 41–44" | 165–167.5 cm 63–66" |
Do not choose Mondor leotards from the age label alone. The Canadian age notation can fit differently from the European gymnastics sizing many customers are familiar with. Use girth first, then bust/chest and waist, and treat the age as a secondary reference.
How to Measure for Mondor Gymnastics Leotards
Measure over underwear or close-fitting clothing using a flexible tape measure. Stand naturally and keep the tape comfortably against the body without pulling it tight.

Girth
Key MeasurementStart at the centre of one shoulder. Bring the tape down the front of the torso, through the crotch and back up to the same shoulder in one complete loop.
For Mondor leotards, girth is the most useful measurement when age and body measurements suggest different sizes.
Bust / Chest
Measure around the fullest part of the bust or chest, keeping the tape level around the body without compressing it.
Waist
Measure around the natural waist, usually the narrowest part of the torso. Keep the tape comfortably close and level.
Hips
Measure around the fullest part of the hips and seat while standing naturally. Keep the tape level all the way around.
Height
Stand straight without shoes, with feet flat on the floor, and measure from the floor to the top of the head.
Mondor does not use height in this garment chart, but it can help when considering overall proportions and torso length.
Mondor's Canadian size labels can appear larger or smaller than expected when compared with familiar European age or numbered gymnastics sizes. Dance World therefore recommends choosing from the actual measurement chart rather than the age printed on the garment. Our familiar-size references are based on fitting experience and are intended to help customers interpret the chart, not replace Mondor's published measurements.

Mondor 7811 Mallard Gymnastics Biketard – Design & Performance
The 80% nylon and 20% elastane fabric has a smooth surface with a gentle sheen. Flexible stretch continues through the body and short legs, allowing for reaching and bending during practice. The comfort gusset is another practical detail within the simple one-piece construction.
The Mallard design combines pale aqua and deeper teal tones in sweeping panels across the front. Curved and diagonal lines give each section a clear shape, while the back features a simpler division between lighter and darker fabric. The fabric’s sheen brings out these changes in tone as the gymnast moves.
The short legs have a 2-inch inseam, adding coverage over the tops of the thighs without needing a separate pair of shorts. Broad shoulder straps, a round front neckline and a scoop back complete the sleeveless shape. A matching scrunchie brings the outfit together for class, making the 7811 a practical option for children who prefer a little more leg coverage.

What Is a Gymnastics Biketard?
A biketard combines the body of a leotard with short legs in one piece. You may also see it called a short unitard. It offers extra coverage over the tops of the thighs and can suit children who enjoy the feel of shorts for gymnastics.
Check your club’s clothing requirements before choosing. When trying it on, ask your child to reach overhead and bend gently at the hips and knees. The body should allow comfortable movement, and the leg hems should sit neatly without digging in. Choose using current measurements and the size guide, paying particular attention to torso girth.
