Size guide

Get the right size the first time

Most kids ninja suits are sized by height in centimeters, while adult styles list their own size range. Three quick steps and you are ready to order.

  1. Measure their height

    Stand them against a wall with shoes off and measure from the top of the head to the floor.

  2. Match the size chart

    Compare that number to the size options on the product page and any size chart in the product photos.

  3. Between sizes? Size up

    A little extra room means easy movement and space for warm layers on a cold Halloween night.

FAQ

Ninja costume questions, answered

Sizing, shipping, returns and what comes in the box.

What size ninja costume should I buy for my child?

Most kids ninja suits are sized by height in centimeters, such as 110, 120 or 130 cm. Measure your child's height with shoes off, match it to the size options on the product page, and size up if they fall between two sizes so the costume fits over clothes.

Do your ninja costumes come with a mask?

Many do, but not all. Each product title and description lists what is included. Several kids sets include a mask or headpiece, a belt or sash, and toy accessories.

Are the weapons included with kids' costumes real?

No. Weapon pieces included with kids costumes are toy props made from foam or plastic. As with any toy, supervise young children during play.

What is the difference between a ninja costume and a samurai costume?

A classic ninja suit is dark and stealthy, usually with a hood or face mask and a sash. A samurai costume takes inspiration from samurai armor and kimonos, often with bolder colors and layered details. Many styles blend the two.

Do you carry adult and pet ninja costumes?

Yes. We carry men's and women's ninja and samurai costumes for adults, and ninja costumes for pets so the family dog can join in.

How long does shipping take?

Most orders ship within 1 to 5 business days and arrive within 5 to 21 business days, depending on where the item ships from. You will receive a tracking email when your order ships.

Will my costume arrive in time for Halloween or my event?

If you need a costume by a certain date, we recommend ordering at least 4 weeks ahead. Delivery times are estimates, and carriers get busy before Halloween.

What is your return policy?

If your item arrives damaged, defective or is not what you ordered, contact us within 30 days of delivery with your order number and photos, and we will send a replacement or a full refund. We cannot accept change-of-mind or wrong-size returns, so please check the sizing details before you order.
