The short answer
When meio means half of something, it can agree with the noun: meio litro (half a liter), meia hora (half an hour).
Use meio or meia for “half”
The agreement is especially easy to notice with time and measurements. Match the ending to the noun that follows.
A aula dura meia hora.
The class lasts half an hour.
Quero meio quilo de tomates.
I’d like half a kilo of tomatoes.
Ela comeu meio sanduíche.
She ate half a sandwich.
Keep meio unchanged before an adjective
When meio means rather, somewhat, or a bit, it works as an adverb and stays meio, even before a feminine adjective: ela está meio cansada.
This distinction is about what the word modifies. Half of a feminine noun uses meia; a bit tired uses meio because it modifies the adjective.
Estou meio perdido com esse formulário.
I’m a bit lost with this form.
A gente ficou meio surpresa.
We were somewhat surprised.
O café está meio frio.
The coffee is a bit cold.
Check whether a noun follows
Ask whether meio refers to half of a countable amount or softens an adjective. The word after it often gives you the clue.

I’ll wait half a week.
Ela parece meio preocupada.
She seems a little worried.
Falta meia página.

Put it into practice
Use meia before a feminine noun when you mean half; use meio unchanged when you mean a bit or somewhat.
