Will the bag make the cabin? Know tonight, not at the gate.

The checker at carryonsize.com carries the cabin dimensions and weight limits of over a hundred carriers. What follows is a walk through what the gate actually checks on Australian flights — the frame, the scale and the screening point.

Six panels, and the bag is decided

A cabin bag card answers one question per panel. The size checker answers the frame panel; the other five are the ones that catch people at the airport.

01

Personal item

The small bag that rides under the seat in front — laptop bag, handbag or slim pack. Most Australian fares include one next to the main bag, and the checker counts both.

02

Main bag

The overhead bag. The long-standing Australian frame is 56 × 36 × 23 cm, and the bag has to sit inside it exactly as it stands.

03

The frame

The sizer at the gate is the referee: no squashing, no rounding down. Wheels, handle and the packing inside are all measured with the bag.

04

The scale

Weight is the second gate. Most economy fares carry a 7 kg cap, and a soft bag that passes the frame can still fail the scale.

05

The screening point

On international departures: 100 ml or 100 g per container, in one clear resealable bag. Most domestic flights carry no liquid limit at all.

06

If it fails

Tagged for the hold at the gate, for a fee set by the airline — or repacked on the spot. Spare batteries come out either way.

the storythe night before

The weight the frame never sees

Kellie Barnes had measured her roll-aboard at home, and it passed the frame at Melbourne Airport without a second look — upright, handle folded, wheels on the floor. The number that ended the argument was a different one. At the gate the bag went onto the scale, and the display settled at 9.2 kg.

Her fare was the cheapest seat on the Friday run to Cairns, and it carried a 7 kg cabin allowance. The frame had cleared the bag. The scale had not. Repacking at the desk, in front of a boarding queue, took eleven minutes and most of her patience.

The frame checks one number and the scale checks the other — and it is the second one that most bags fail.
— Kellie, after the return leg

There was nothing exotic in the bag: a camera, two chargers, running shoes and a wash kit, about two kilos more than the allowance. The laptop moved to the personal item under the seat; the shoes and the toiletries went into the checked suitcase she was already paying for. The fee at the desk disappeared with the weight.

On the way home she did the arithmetic before the taxi arrived. The checker at carryonsize.com lists both numbers for each airline — the frame dimensions and the weight cap — alongside the screening notes, so the repacking happened on the bed at home instead of at the desk. Two numbers decide the bag, and both are published before you pack.

Three frames cover most Australian cabins

Airlines publish the frames their gates use. These are the three that appear across Australian domestic and trans-Tasman flying — the figures the checker sorts by.

A note on the numbers

The frame is half the check.

Most economy fares set a 7 kg cap across the cabin allowance, flexible fares carry more, and no single bag goes over 10 kg for safety. The cap is the number most bags fail — the checker lists it next to every frame.

Frames, weights and fees are set by each airline and revised over time. The checker at carryonsize.com holds the current figures per carrier; the airline’s own page is the final word.

packing methodthree moves

Pack to the frame before you pack the bag

01

Stand it up

Measure the bag upright, wheels on the floor, handle folded — the way the gate sees it, not the way it lies on a bed.

02

Pack it as it boards

Fill the bag the way it will travel. An empty bag measures smaller than a packed one, and a soft bag bulges.

03

Read the tallest numbers

Compare the tallest true measurement with the airline’s frame, and put the bag on a scale at the same time. Both numbers, one verdict.

The checker runs this comparison for more than 100 airlines — carryonsize.com

Before the gate does the number

Take the frame and the weight off the airline’s list

The checker at carryonsize.com is free and needs no account: pick the airline, read the frame and the cap, pack once. This page is the background; the checker is the answer.

Six answers about the same bag

01 Which number fails more bags: the frame or the weight?

The weight, by a distance. Most bags are sold inside the common frames; it is the packed weight that pushes them over the cap. Check both, but weigh last, when the bag is full.

02 What happens if the bag fails at the gate?

The airline decides. The common outcomes: the bag is tagged for the hold and charged a gate fee, or items move into the personal item on the spot. The fee is set by the airline, not by the airport.

03 Do the liquid limits apply on domestic flights?

Mostly no. The 100 ml container rule applies at international departures and on transits; most domestic flights carry no liquid limit. It bites when a domestic leg connects to an international one.

04 Where do spare batteries and power banks go?

The cabin, always. Spare lithium batteries and power banks never travel in checked baggage, and a unit above the common 100 Wh threshold needs the airline’s approval in advance.

05 Does the checker cost anything?

No. It is a free reference with no account and no checkout: look up the airline, read the frame and the cap, close the tab.
