What Size Should My Baby Wear? (Complete Baby Size Guide for Parents in Egypt)
What Size Should My Baby Wear?
A complete baby size guide for parents in Egypt — so picking the right fit for your little cub feels easy, every time.

Choosing the right baby clothing size should feel simple, but for many parents it quickly becomes confusing. Sizes vary across products, age ranges overlap, and babies grow faster than expected. Ordering the wrong size leads to frustration, unnecessary returns, and wasted money.
This guide explains exactly what size your baby should wear, how baby sizing actually works, and how to choose the correct fit with confidence — every time you shop.
Understanding Baby Clothing Sizes
Baby clothes are typically labeled by age ranges such as:
At Cubbies, you'll find sizes that follow this structure — sometimes combined into broader ranges depending on the product design. This gives you flexibility in fit, but it also means sizing isn't always exact.
The most important thing to remember:
Baby clothing sizes are guidelines, not precise measurements.

What Actually Determines Your Baby's Size
Relying on age alone is the most common mistake parents make. The correct size depends on three key factors:
Weight
Babies of the same age can vary significantly in weight. A heavier baby will often need a larger size, even if they're younger.
Height
Longer babies may need a size up to stay comfortable, especially in full outfits or one-piece garments.
Body Shape
Some babies have a fuller build while others are slimmer. Fit can vary depending on the cut of the clothing.
When choosing baby clothes, always consider these factors alongside the age range.
Baby Size Chart
By age, weight & height
| Size | Age | Weight | Height |
|---|---|---|---|
| Newborn | 0–1 month | 2.5–4 kg | 45–55 cm |
| 0–3 M | 0–3 months | 3–6 kg | 50–60 cm |
| 3–6 M | 3–6 months | 5–8 kg | 60–67 cm |
| 6–9 M | 6–9 months | 7–9 kg | 65–72 cm |
| 9–12 M | 9–12 months | 8–10 kg | 70–76 cm |
| 12–18 M | 12–18 months | 9–11 kg | 75–82 cm |
This chart reflects standard baby sizing used across many brands and gives you a reliable starting point. But here's the most important tip we can share with you:
Always Check the Size Chart on Every Product
Every Cubbies piece is tailored a little differently. Before you add anything to your cart, click the Size Chart button on the product page — those measurements are made specifically for that item, and they're the most accurate way to find the perfect fit for your little cub.

Why Baby Sizes Feel Inconsistent
Many parents notice that the same size can fit differently across products. Here's why:
Different Product Types
Fitted items like bodysuits are designed to sit closer to the body, while sets and outerwear leave more room for movement.
Wider Age Ranges
Some products cover extended ranges like 0 to 9 months or 3 to 18 months. They're designed for flexibility, but can feel less precise.
Rapid Growth
Babies grow quickly and unpredictably. A size that fits today may feel tight within weeks.
Understanding these differences will help you make better sizing decisions — and reinforces why checking each product's individual size chart matters so much.
The Most Reliable Rule
If you're unsure between two sizes, choose the larger size.
A slightly bigger fit gives you:
- Longer wear as your baby grows
- Greater comfort and flexibility
- Less risk of returns or exchanges
Clothing that's too small can't be used. Clothing that's slightly larger stays practical — and usually gets worn the most.

How to Choose the Right Size When Shopping Online
When shopping for baby clothes online, follow this simple process:
1. Check the Size Range
Review the age range listed on the product page and compare it with your baby's current stage.
2. Open the Size Chart Button
This is the most important step. Every Cubbies product has its own size chart with the exact measurements for that piece — always check it before you order.
3. Consider the Fit
Structured pieces and tighter designs may need sizing up. Relaxed sets usually fit true to size.
4. Review Product Details
Look for notes about fabric, stretch, and intended use. Lightweight summer pieces may fit differently than layered or winter items.
A few extra seconds reviewing these details can save you a return.
Size Guidance by Age Stage
Don't Over-Buy
Babies outgrow these sizes quickly. A few essentials are usually all you need.
Steadier Growth
Growth begins to stabilize. A safer stage to invest in multiple outfits.
Movement Begins
Mobility increases. Consider sizing up to allow room for crawling and play.
Little Walkers
Fit matters more as babies start walking. Comfort and freedom of movement come first.
Common Sizing Mistakes to Avoid
- Choosing sizes based only on age
- Ignoring weight and height differences
- Buying too many newborn items
- Overlooking product-specific fit details
- Skipping the Size Chart button on individual products
Avoiding these mistakes will help you choose sizes more accurately and reduce returns.

A Smarter Way to Shop Baby Clothes
A practical approach is to buy for the next stage rather than the current one.
For example, if your baby is close to 6 months, choosing a 6 to 9 month size — or even 9 to 12 months — can extend usability and improve value.
This approach matches how babies actually grow and ensures every purchase lasts longer.
Three Things to Remember
-
1
Age is a guideline, not a rule
-
2
Weight and height give better accuracy
-
3
When in doubt, size up — and always check the Size Chart button
With this approach, you can shop with confidence and keep your little cub comfortable as they grow.
