KLM publishes in centimetres: hand baggage 55 x 35 x 25 cm including handles and wheels, small bag 40 x 30 x 15 cm. Inches converted here.
KLM's 21.7 x 13.8 x 9.8 in works out to about 2935 cubic inches (48.1 litres) of cabin allowance, which ranks 12 of 22 among the airlines we have verified, about 1% less than the median carrier.
No other airline in our set publishes exactly 21.7 x 13.8 x 9.8 in, so a bag bought specifically for KLM is not automatically safe elsewhere — check before you fly a different carrier.
11 of the airlines we track allow a larger bag and 10 allow less, so a bag sized to KLM clears roughly 50% of the carriers here.
Common bag sizes measured against KLM's published limit. Every figure includes wheels and handles, which is where most bags lose.

KLM allows a personal item up to 15.7 x 11.8 x 5.9 in alongside the 21.7 x 13.8 x 9.8 in carry-on. Both are included in the fare, so the practical question is only whether each bag is within its own limit.

KLM publishes a cabin weight limit of 26 lb (12 kg). 12 kg COMBINED across the hand baggage and the small bag in Economy (18 kg in Business) — not a per-bag limit.
Up to 15.7 x 11.8 x 5.9 in. KLM calls it a small bag: 40 x 30 x 15 cm.
Yes. KLM measures the bag including wheels, handles and any external pockets, which is why a bag sold as “22 inch” can still measure over.
