When to use the present tense of medir

The present tense is not one single use — it covers several situations, and medir appears in all of them. The five uses below are the ones you will meet most often, each with an example that shows the verb in a natural sentence.

Habits and routines

The present describes things that happen regularly, as a habit or routine.

"Cada día, yo mido la habitación con una cinta" — "Every day, I measure the room with a tape measure"

General truths

The present states facts that are always true, not just true today.

"Mi amigo mide la temperatura del agua" — "My friend measures the water temperature"

What is happening now

The present describes an action in progress right now.

"Ahora, yo mido dos metros de tela" — "Right now, I measure two metres of fabric"

Near-future plans

Spanish often uses the present for a plan that is already fixed.

"Mañana, nosotros medimos el tiempo con un cronómetro" — "Tomorrow, we measure the time with a stopwatch"

Timetables and scheduled events

The present is the tense for timetables, programmes and things that happen on a schedule.

The present tense vs the closest tenses

Present — habit or general fact vs Preterite — one finished occasion

The present describes a habit, a routine or a general fact — something that happens again and again or that is true in general. The preterite reports one finished occasion in the past. Use the present when the action repeats or is still true, and the preterite when you are telling what happened once, on a specific day.

  • Present — habit or general fact: {'pre_es': 'Cada día, ', 'pre_en': 'Every day, '}yo mido la habitación con una cinta — "I measure the room with a tape measure"
  • Preterite — one finished occasion: {'pre_es': 'Ayer, ', 'pre_en': 'Yesterday, '}yo medí la habitación con una cinta — "I measured the room with a tape measure"

Present — now vs Imperfect — a past habit or background

The present talks about now. The imperfect talks about the past as a background — a repeated habit, an ongoing situation, something that used to happen. If you can add "used to" in English, the imperfect is usually the right choice; if it is happening now or always, use the present.

  • Present — now: {}tú mides la temperatura del agua — "You measure the water temperature"
  • Imperfect — a past habit or background: {}tú medías la temperatura del agua — "You used to measure the water temperature"

Present — now or a fixed plan vs Future — what will happen

The present describes what happens now, what you do regularly, or a plan that is already fixed. The future describes what will happen later — a promise, a prediction, a plan that is not yet under way. Spanish often uses the present for near-future plans, but the future is the form for a clear statement about tomorrow.

  • Present — now or a fixed plan: {'subj_es': 'Mi amigo', 'subj_en': 'My friend'}él mide dos metros de tela — "He measures two metres of fabric"
  • Future — what will happen: {'subj_es': 'Mi amigo', 'subj_en': 'My friend'}él medirá dos metros de tela — "He will measure two metres of fabric"

Common mistakes with medir in the present tense

These are the errors learners actually make with medir in the present tense. Each one shows the wrong form, the right form, and why the right form is right.

✗ *Yo medo la habitación con una cinta.

✓ Correct: Yo mido la habitación con una cinta.

medir is a stem-changing verb (e → i): the stem vowel changes in the stressed present forms, so the yo form is mido, not medo.

✗ *Tú mide la temperatura del agua.

✓ Correct: Tú mides la temperatura del agua.

The tú form and the él form are different: tú takes mides, él takes mide.

✗ *Cada día, yo medí dos metros de tela

✓ Correct: Cada día, yo mido dos metros de tela

Cada día describes a habit, so it needs the present, not the preterite.

✗ *Vosotros medis el tiempo con un cronómetro.

✓ Correct: Vosotros medís el tiempo con un cronómetro.

The vosotros present form carries a written accent: medís, not medis.
