Use this Mayoral size guide from Just Kidz Galway to find the right fit before you order. Mayoral is a Spanish family brand that uses the European sizing system — sizes go by age (months for newborn, years for mini and kid) and reference your child’s height in centimetres. The numbers below are taken from the official Mayoral size chart and apply across most of their newborn, mini and kid product lines.

Mayoral newborn sizing (0–36 months)
Mayoral newborn sizes are labelled in months and refer to your baby’s approximate age. Each size corresponds to a height range. If your baby sits between sizes, we always recommend going up a size — babies grow fast and Mayoral fits true to size.
| Mayoral size | Approx. age | Height (cm) |
|---|---|---|
| 0–1 m | 0–1 month | 50–55 |
| 1–2 m | 1–2 months | 55–60 |
| 4 m | 3–4 months | 60–65 |
| 6 m | 5–6 months | 65–70 |
| 9 m | 7–9 months | 70–74 |
| 12 m | 9–12 months | 75–80 |
| 18 m | 12–18 months | 80–86 |
| 24 m | 18–24 months | 86–92 |
| 36 m | 24–36 months | 92–98 |
Mayoral mini sizing (2–9 years)
Mini covers the bulk of the Mayoral kids’ clothing range — everyday tops, bottoms, dresses, dungarees and outerwear. Sizes are labelled by age in years.
| Mayoral size | Approx. age | Height (cm) |
|---|---|---|
| 2 | 2 years | 92–98 |
| 3 | 3 years | 98–104 |
| 4 | 4 years | 104–110 |
| 5 | 5 years | 110–116 |
| 6 | 6 years | 116–122 |
| 7 | 7 years | 122–128 |
| 8 | 8 years | 128–134 |
| 9 | 9 years | 134–140 |
Mayoral kid sizing (10–18 years)
Mayoral’s older-kid range continues the European convention — size = age in years.
| Mayoral size | Approx. age | Height (cm) |
|---|---|---|
| 10 | 10 years | 140–146 |
| 12 | 11–12 years | 146–152 |
| 14 | 13–14 years | 152–160 |
| 16 | 15–16 years | 160–168 |
| 18 | 17–18 years | 168–172 |
How to measure your child for Mayoral clothing
Always measure your child standing straight against a wall, in their underwear, with feet flat. Pencil-mark the top of their head, then measure from the floor to the mark with a tape. Use that height (in cm) to read across to the matching Mayoral size in the tables above.
For best fit, also note your child’s chest and waist measurements. Mayoral garments are cut on the slimmer side compared to UK high-street brands — if your child is taller for their age or has a fuller fit, size up.
Tips for choosing the right Mayoral size
- Buy ahead for newborns. Babies outgrow 0–1 month sizes in 2–4 weeks. We recommend stocking 1–2 m and 4 m for actual day-to-day wear.
- European fit runs slim. If you’re between sizes or your child is on the taller end, size up.
- Allow growing room for occasion wear. Communion suits, christening outfits and Christmas dresses are often worn once — size up so the outfit isn’t tight on the day.
- Knitted and stretch fabrics fit more generously than woven cottons. Check the product page for fabric details.
Mayoral size guide FAQs
Are Mayoral sizes the same as UK / Irish high-street sizes?
No. Mayoral uses the European/Spanish system — size labels match the child’s age and reference height (in cm). UK brands like Next or M&S typically size by age too but with British fit blocks, so a Mayoral 4 will not necessarily match a Next age-4 piece. Always cross-check with the height chart above.
Does Mayoral run small or large?
Mayoral generally fits true to the height column on the chart. Where children are tall for their age or between sizes, we recommend sizing up. Mayoral knitwear and stretch fabrics tend to fit more generously than woven cottons.
What size Mayoral should I buy for a 3-month-old?
For a baby around 60–65 cm tall (approximately 3–4 months old), the Mayoral 4 m size is typically the best fit. Always sense-check against your baby’s actual height in cm rather than age alone — babies vary widely.
What does the Mayoral size ‘mini’ or ‘kid’ mean?
Mayoral’s catalogue is split into newborn (0–36 months), mini (2–9 years) and kid (10–18 years) ranges. Each range has its own designs and fits, but all use the same age/height-based size labels.
