Best YETI® for School: Kids Bottle Size and Engraving Guide
The 12 oz YETI® Rambler® Kids Bottle is the best starting point for younger school children.
It is smaller than adult bottles, includes a straw lid and can be permanently engraved with the child’s name to make it easier to identify.
Older children who need more water may prefer an 18 oz straw bottle.

Best for Younger Children: 12 oz Kids Bottle
The 12 oz kids bottle holds approximately 355 mL and is designed for children aged three and older.
YETI describes it as:
- Dishwasher safe
- Double-wall vacuum insulated
- Leakproof when closed
- Made from stainless steel
- Sized for children
YETI also notes that the straw cap can open when heavily shaken or jostled, so it should be closed carefully and ideally stored upright or in an external bottle pocket.
Best for Older Children: 18 oz Straw Bottle
An 18 oz straw bottle provides more capacity for:
- Older primary school students
- High school students
- Sport days
- Hot weather
- Excursions
- Longer school days
- Children who drink more water
The larger bottle will be heavier when full, so consider the child’s age and how far it needs to be carried.

What Size Should You Choose?
Choose the 12 oz kids bottle when:
- The child is younger.
- The bottle needs to be light and compact.
- There are regular opportunities to refill it.
- It needs to fit a smaller bottle pocket.
- The child prefers a smaller product.
Choose an 18 oz straw bottle when:
- The child is older.
- More water is required.
- The school has limited refill opportunities.
- The bottle will be used for sport.
- The child already handles larger drinkware comfortably.
Why Engrave a Child’s Name?
School drink bottles are frequently misplaced or confused with similar products.
Permanent engraving can help identify:
- First name
- First name and surname
- Initials
- Class
- School house
- Parent contact number
- Sporting team
- A distinctive personal design
Unlike stickers or written labels, engraving will not peel away or wash off during normal use.
Where Should the Name Be Positioned?
The name should be:
- Large enough to read
- Positioned prominently
- Written in a clear font
- Spelled correctly
- Contrasted against the selected bottle colour
- Separate from highly detailed artwork
Avoid using an overly decorative font when quick identification is the priority.
Should You Add a Phone Number?
A parent or guardian may choose to add a contact number to help recover a lost bottle.
For privacy, consider engraving:
- A surname and phone number
- A first name and parent’s number
- Initials and a contact number
Avoid including unnecessary personal information such as a full home address.
Best Children’s Engraving Ideas
Popular designs include:
- Dinosaurs
- Animals
- Trucks
- Construction machinery
- Flowers
- Butterflies
- Mermaids
- Fishing designs
- Sporting artwork
- Space designs
- Initials
- Favourite hobbies
- Children’s drawings
The child’s name should remain the most prominent element when identification is important.
Is a Straw Lid Best for School?
A straw lid allows a child to drink without tipping the entire bottle.
It is convenient for:
- Classroom use
- Lunch breaks
- Sport
- Excursions
- Car travel
- Younger users
The lid should be fully closed before the bottle is placed in a bag.
YETI advises against using its straw-cap bottles for hot, carbonated or pulpy drinks.
How Should the Bottle Be Packed?
To reduce leaks:
- Close the straw mouthpiece completely.
- Check that the lid is correctly tightened.
- Keep the bottle upright.
- Use the external bottle pocket where possible.
- Avoid packing it beneath heavy books.
- Check seals and straw parts regularly.
- Clean the bottle after each school day.
No drink container should be placed beside electronics or important books without additional protection.
Can You Engrave a Kids Bottle You Already Own?
Yes. A suitable existing YETI® can be personalised through our BYO YETI® engraving service.
This is useful when the bottle:
- Was received as a gift
- Already matches the school colours
- Is a discontinued colour
- Needs a name before school starts
- Is being passed to a younger sibling
Final Recommendation
Choose the 12 oz YETI® Kids Bottle for younger children and the 18 oz straw bottle for older children who need more capacity.
Make the child’s name large, clear and easy to recognise.
