How to choose the right size of snowsuit for a child?

Finding the right snowsuit size for your child is essential to help them make the most of winter! A well-fitting suit helps retain heat, promotes freedom of movement, and allows little adventurers to play comfortably in the snow.

But with different sizes, growth spurts, and adjustable styles, how do you make the right choice?

Discover our tips for choosing the ideal snowsuit size for your baby or child without compromising their comfort or protection from the cold.

What snowsuit size should you choose for a child?

The right snowsuit size corresponds to your child's current measurements while leaving enough room to move and wear appropriate winter clothing.

A suit that is too small can restrict movement and become uncomfortable. Conversely, a style that is much too large may hinder movement and allow snow to enter through the openings.

To find the right balance, consider three factors:

• Your child's height and measurements: they are more reliable than age alone.

• The room needed to move: your child should be able to run, crouch, and raise their arms comfortably.

• Adjustment options: an adjustable snowsuit can grow with your child without having to choose an excessively large size from the start.

At Souris Mini, our snowsuits are designed to accompany children on their winter adventures, with practical adjustments that promote comfort and freedom of movement.

How to measure your child before buying a snowsuit?

Before choosing a size, take a few minutes to measure your child. This step is particularly useful when shopping for a snowsuit online.

1. Measure their height

Ask your child to stand barefoot with their back straight against a wall.

Measure the distance from the floor to the top of their head. Record the result in centimeters.

2. Measure their chest circumference

Using a flexible measuring tape, measure around the chest at its widest point without pulling too tight.

This measurement helps you choose a coat that offers enough room for the layers worn underneath.

3. Measure their waist and hips

Measure around the natural waist, then around the hips at their widest point.

These measurements are particularly useful for choosing a two-piece snowsuit with pants or overalls.

4. Consult the Souris Mini size guide

Once you have taken the measurements, compare them to our Souris Mini size guide.

Our tip: do not rely solely on the age indicated on the label. Two children of the same age may have very different body types.

How to tell if a snowsuit is the right size?

Even when the size matches your child's measurements, it is important to check the fit.

Here are a few simple tests to perform when they wear their snowsuit.

The arm test

Ask your child to raise their arms above their head.

The sleeves should remain long enough to protect their wrists without pulling excessively on their shoulders.

The leg test

Invite your child to crouch, bend their knees, and take a few steps.

The pants should allow these movements without riding up excessively or pulling at the crotch.

The comfort test

Check that your child can move freely in the clothes they will normally wear under their snowsuit.

They should not feel any significant tension at the shoulders, chest, waist, or knees.

The opening test

Make sure the wrists, ankles, and collar provide adequate protection.

A good fit helps limit snow and cold air from getting in during outdoor play.

Should you buy a snowsuit one size larger?

This is a question many parents ask!

When we know how quickly children grow, it can be tempting to buy a much larger snowsuit so that it lasts longer.

However, consistently choosing a larger size is not always the best solution.

A suit that is too large can hinder freedom of movement, especially when the child is running, climbing, or playing in the snow.

The ideal is to choose a size suited to their measurements and to favor a style that offers adjustment options.

This is precisely one of the advantages of adjustable snowsuits.

Why choose an adjustable snowsuit for a child?

An adjustable snowsuit is designed to adapt to the child's growth through various adjustment systems.

At Souris Mini, our adjustable snowsuits are designed to accompany little ones on their winter adventures while promoting comfort and durability.

Depending on the style, several features make adjustment easier:

• Adjustable sleeves: to adapt their length to the child's growth.

• Adjustable legs: to better adapt the length of the pants.

• Adjustable waist: for a comfortable fit.

• Adjustable straps: to adapt certain overalls to the child's body type.

These details allow you to make better use of the snowsuit as your child grows, without unnecessarily compromising comfort.

A well-chosen adjustable style can thus be worn longer, depending on the child's growth and the condition of the garment.

How to choose the size of a snowsuit for a baby?

For a baby, comfort and ease of dressing are particularly important.

Since babies move differently than older children, you should choose a style suited to their body type and needs.

To select the right size:

• Consult your baby's measurements rather than relying solely on their age in months.

• Check that the suit does not constrict their arms, legs, or torso.

• Favor a style that is easy to put on and take off.

• Make sure the garment allows for natural movement.

Important: a thick snowsuit should not be worn under the straps of a car seat. For car travel, follow the manufacturer's recommendations for the car seat and use appropriate thin layers, with a blanket placed over the straps when needed.

One-piece or two-piece snowsuit: does the size change?

The selection criteria are similar, but certain points deserve special attention depending on the style.

One-piece snowsuit

For a one-piece suit, pay particular attention to the length of the torso and the room in the crotch.

Your child should be able to crouch and raise their arms without feeling excessive tension.

Two-piece snowsuit

For a style consisting of a coat and overalls, check the fit of each part.

The coat should adequately cover the upper body, while the pants should allow them to walk and bend their knees easily.

The straps and adjustment systems can help achieve a better fit.

The best choice depends above all on your child's age, body type, and winter activities.

When should you change the size of the snowsuit?

During the winter, children can grow quickly. It is therefore useful to regularly check the fit of their snowsuit.

Certain signs may indicate that it is becoming too small:

• The sleeves no longer sufficiently cover the wrists.

• The pants ride up excessively when the child crouches.

• The garment pulls at the shoulders or crotch.

• The child seems less comfortable running, climbing, or playing.

• The adjustment systems no longer allow for a comfortable fit.

Before changing sizes, check if the adjustable features of the style can still be used.

Frequently asked questions about snowsuit sizes

How to choose the size of a snowsuit for a child?

Measure your child's height, chest circumference, waist, and hips, then consult the brand's size guide. Choose a size that allows them to move freely and wear appropriate winter layers.

Should a snowsuit be large?

A snowsuit should offer enough room to move, but it should not be excessively large. A fit that is too loose can hinder movement and reduce protection at the openings.

Should you take a size up for a snowsuit?

Not necessarily. It is better to choose according to the child's measurements and the manufacturer's instructions. An adjustable snowsuit can offer room to adjust without requiring a size that is much too large.

How to tell if a snowsuit is too small?

If the sleeves or pants ride up excessively, the garment pulls when the child moves, or it becomes difficult to crouch, the suit may be too small.

Are Souris Mini snowsuits adjustable?

Yes. Souris Mini snowsuits feature adjustable features that allow their fit to adapt to the child's growth. Depending on the style, these include adjustable sleeves, legs, waist, or straps.

How to choose the size of a snowsuit for a baby?

Refer to your baby's current measurements and the size guide rather than their age alone. Favor a comfortable fit that is not constricting and suited to their movements.
