Size Guide
A softer way to find the right fit.
Kidluna sizing is designed for real childhood movement: sitting, stretching, running, layering, and growing. Use this guide to compare body measurements, choose a comfortable fit, and keep everyday outfits feeling easy.
Three simple checks before choosing a size.
For the most comfortable Kidluna fit, use a soft tape measure and keep it level. If the child is between sizes, choose the larger size for longer wear, easier layering, and more room to move.
Kidswear size reference.
This chart is a general guide for Kidluna everyday clothing. For relaxed pieces such as tees, overalls, one-pieces, dresses, activewear, and cozy layers, allow a little extra room for movement.

How each style should feel.
Different pieces are meant to fit differently. A tee can sit relaxed, swimwear should stay secure, and outerwear needs room for a layer underneath.
Tees & short sleeves
Choose a size that leaves gentle room across the chest and shoulders. A slightly relaxed fit helps with daily movement and repeated washing.
Soft everyday comfortSwimwear & activewear
Look for a close but comfortable fit. The garment should stay in place while the child bends, jumps, swims, and plays.
Secure movement fitOveralls & one-pieces
Check both height and torso length. If the child is tall for their age, sizing up often creates a more natural, easy fit.
Room through the bodyOuterwear & cozy layers
Allow space for a tee, sweatshirt, or set underneath. Sleeves can be gently rolled if the child is between sizes.
Layer-friendly sizing
Before the tag comes off.
Try the outfit on over light underlayers. Ask the child to sit, reach, bend, and take a few playful steps. The best size should feel easy without pulling at the shoulders, waist, seat, or sleeves.
Small details that make sizing easier.
Use age as a starting point, then confirm with height, chest, and waist. Kids grow fast, so a touch of extra room is usually better for everyday clothing.
Should I choose by age or body measurement?
Body measurements are more reliable than age. Age ranges are helpful as a quick reference, but height, chest, and waist give a more accurate fit for Kidluna clothing.
What should I do if my child is between sizes?
Choose the larger size for everyday tees, overalls, one-pieces, dresses, outerwear, and cozy layers. For swimwear or activewear, check that the larger size still feels secure.
How much room should outerwear have?
Outerwear should allow one comfortable layer underneath without pulling at the shoulders or sleeves. A slightly roomy fit also supports longer seasonal wear.
Can I ask for help before ordering?
Yes. Contact Kidluna with the child’s height, chest, waist, and the style you are considering. We will help you choose the most comfortable size.
