Okaïdi Size Guide: Finding the Right Fit for Every Child

Welcome to the essential Okaïdi Size Guide. We provide accurate, easy-to-use size charts to help you confidently select the perfect fit, whether you are shopping for your own child or choosing a special baby gift. Accurate sizing is key to comfort and confidence, especially for children who are growing fast. Our detailed guide, informed by years of experience as a premier baby store and retailer, simplifies shopping and helps reduce the need for returns.

Shopping for kids clothing is easier — and more accurate — when you know exactly what size you need. At Okaïdi Cyprus, our detailed size guide helps parents, family members, and gift-givers find the perfect fit across all ages and stages, from newborns to teenagers.

Our guide covers all categories of baby and kids clothing, including bodysuits, rompers, tops, trousers, dresses, coats, and shoes. For babies, we provide guidance by age (0–3 months, 3–6 months, etc.), weight, and length to make sure the garments feel just right from the very first wear. Whether you’re shopping for essentials or choosing a thoughtful baby gift, accurate sizing makes all the difference.

Toddlers and older kids have their own needs as they grow. That’s why our sizing also includes easy conversion charts for height, chest, and waist measurements, so parents can shop confidently as their children move from one size to the next. Our pieces are designed with extra flexibility in mind — think stretch waistbands, adjustable straps, and room to grow — so they’re forgiving even during growth spurts.

If you’re unsure between two sizes, we generally recommend sizing up. Okaïdi garments are made with smart tailoring to ensure the clothes still fit well without looking oversized. For items like outerwear or shoes, this also gives your child more time to wear their favorite pieces through changing seasons.

We also include fit notes for specific categories. For example, our baby bodysuits have a snug fit to stay in place during sleep, while our girls’ dresses offer a relaxed silhouette for movement. These tips help you choose not only the right size, but the right feel for each item.

Shopping for someone else’s child? Our guide helps you confidently select a baby gift or birthday present, even if you’re not the parent. Simply ask for the child’s age and general size, check our chart, and you’ll be ready to pick a thoughtful gift that actually fits.

This page is an essential companion when you’re browsing online — especially since kids grow fast, and sizing can vary between brands. We’ve simplified it all in one place to make sure you feel secure in every purchase.

Explore our full size guide today to shop smarter, reduce returns, and ensure your child looks and feels great in every Okaïdi outfit. Whether you're shopping online or visiting us in-store in Cyprus, we've got sizing covered — so you can focus on the fun part.
