Bib, Bowl & Bento Size Guide (AU)

Sizing feels uncertain when you're setting up baby mealtimes for the first time. Is that bowl too big for first tastes? Will the bento size actually work for a toddler lunch? How much neck room does a silicone bib really need?

This guide walks through how to choose the right bento size, bowl size and bib size for each stage, with practical tips for common Australian setups like the Ikea Antilop highchair and daycare lunches.

For a full overview of how feeding sets, bento boxes and highchair placemats fit together, see our Silicone Mealtime Guide (AU).

Quick reference: sizes by stage

Every brand uses slightly different dimensions, but these ranges are a helpful starting point. Always check the actual measurements on the product page before you buy.

How to measure silicone bowls and plates

When comparing silicone bowls and plates, three measurements matter most.

• Diameter or width: how much space the bowl takes up on the tray.
• Height or depth: how easy it is for tiny spoons and hands to reach the food.
• Capacity: roughly how much food it can comfortably hold without overflowing.

First tastes (6 to 7 months)

• Choose a smaller, shallower bowl so baby can see and reach the food easily.
• Low sides help beginners scoop without hitting a wall every time.
• Portions at this stage are tiny. Plan for just a few teaspoons to a couple of tablespoons per meal.

Everyday meals (7 to 18 months)

• Move to a medium bowl or plate that can hold a full meal as portions grow.
• Divided plates help separate textures, but a simple bowl works just as well for many babies.
• Make sure the base fits comfortably on the highchair tray without hanging over the edge.

Toddlers (18 months and up)

• Many toddlers prefer a flatter plate with more room to spread food out and explore it.
• Check that portions fit without being piled too high. Overfilled plates can make food harder to manage.
• If you're still using suction, make sure the base has a good contact area on the tray or placemat.

If your suction plates or bowls are not gripping well, our suction plate troubleshooting guide covers surfaces, soap film and baby hands in more detail.

Choosing the right bento size for babies and toddlers

A bento box does not need to be large. The right bento size simply needs to hold what your child will realistically eat between meals, with compartments shallow enough for little hands to reach.

Bento sizes for babies (around 7 to 12 months)

• Look for a compact bento with a few small compartments, not a full school-sized box.
• It should hold a handful of soft finger foods comfortably without extra space.
• Shallow compartments matter here. Babies cannot dig into deep sections independently.
• Total capacity around 300 to 500 ml across compartments is usually plenty.

Bento sizes for toddlers and daycare (18 months and up)

• Choose a bento that fits a simple main plus 2 to 3 sides. Think half a sandwich or small pasta portion, a few pieces of fruit and a snack.
• Check the external dimensions if it needs to slide into a specific lunch bag or fit inside a daycare cubby shelf.
• Consider the weight when the box is full. Silicone lids and bases are soft, but the filled box still has some heft for small arms to carry.
• A secure but easy-to-open lid is worth checking. Toddlers open their own lunch boxes at many daycare centres.

Total capacity around 600 to 900 ml across compartments suits most toddler daycare lunches without overpacking.

Bib sizes and neck fit: what to check

A good bib is mostly about comfort and coverage. Silicone bibs that are too tight rub at the neck. Bibs that are too loose let food slide straight in. Here is what to look at.

• Neck circumference: choose a bib with multiple button or notch settings so it can fit snugly without digging in as baby grows.
• Coverall length: the bib should reach the chest area where most food lands during self-feeding.
• Pocket size and depth: a slightly deeper pocket catches more food before it reaches the lap or highchair seat.

How to check bib fit at home

• Fasten the bib so you can comfortably fit one finger between the bib and your baby's skin.
• Check for rubbing at the neck folds, shoulders or behind the ears.
• As baby grows, move to the next setting so the fit stays comfortable through toddlerhood.
• If your bib only has one or two settings and baby is already on the widest, it is time to size up.

Will these pieces fit on the Ikea Antilop highchair tray?

The Ikea Antilop tray is one of the most common bases for silicone bowls, plates and placemats in Australian homes. A few quick checks help make sure your pieces fit well.

• Choose bowls and plates that leave a little space around the tray edges so baby can still rest their hands comfortably without bumping the bowl.
• Make sure the suction base sits fully on the flat centre area, not up onto the curved lip at the tray edge. Suction does not seal on curved surfaces.
• If you are using a fitted silicone placemat, place it first, smooth out any air bubbles, then position your bowls and plates on top.
• The Antilop tray measures approximately 53 cm wide by 28 cm deep. A standard silicone placemat designed for the Antilop will account for these dimensions, but always verify before ordering.

If suction is inconsistent on your tray, our guide to suction plates not sticking covers surfaces, soap film and little hands in more detail.

How many pieces do you actually need?

You do not have to own every size at once. Most families find they are comfortable with a straightforward set that covers home, daycare and outings.

• 2 silicone bowls or plates: one in use, one clean or drying.
• 1 silicone bento box: for daycare, outings or meals at grandparents.
• 2 silicone bibs: one for home, one for the nappy bag or daycare bag.

If your routine changes, such as more daycare days or more outings, you can add extra pieces without replacing what you already have. Silicone feeding gear is built to last across multiple stages, so investing in the right sizes from the start pays off.

Keeping your silicone feeding gear in good shape

Sizing is only half the picture. Keeping silicone bowls, bibs and bento boxes clean means they perform better and last longer.

• Rinse bibs and bowls straight after meals before food dries into the silicone surface.
• Silicone is generally dishwasher safe, but check your specific product instructions first.
• Avoid sharp utensils on silicone surfaces. Cuts and nicks can trap food residue over time.
• Store bento boxes with the lid slightly ajar so air can circulate.
