ku-tsu, two beats — both vowels typically devoice, so the word is nearly all friction.
kutsu
Two beats and almost no voicing in either. Like 好き and 靴下, this is a word where the timing is entirely internal — the speaker measures two counts even though a listener hears little more than consonants.

この靴は小さすぎます ends with 小さすぎます, where 小さ carries a long i at its front and すぎます adds four more morae. So a nearly voiceless two-beat noun is followed by a long, fully-voiced verb phrase — maximum contrast in texture.
"KOO-tsoo" rounds and voices both vowels and stresses the first. Spread the lips, let both devoice, and keep the affricate as a single release. Beginners who voice everything make this two-beat word sound as long as a four-beat one.
