Medimos la resolución en píxeles.

Medimos is the 1st person plural form of medir in the present tense, so it means we measure.

• medir = to measure
• yo mido = I measure
• tú mides = you measure
• nosotros/nosotras medimos = we measure

So Medimos la resolución en píxeles uses medimos because the subject is we.

Spanish often omits subject pronouns when they are not needed, because the verb ending already shows who the subject is.

Here, medimos already tells you the subject is we, so nosotros is unnecessary.

You could say:

• Nosotros medimos la resolución en píxeles.

But in normal Spanish, especially in neutral everyday usage, it is more natural to leave nosotros out unless you want to add emphasis or contrast.

It can also be the preterite form of medir, meaning we measured.

So medimos can mean either:

• we measure
• we measured

The form is the same. Context tells you which meaning is intended. In a general statement like Medimos la resolución en píxeles, it is usually understood as the present tense: we measure.

Spanish often uses the definite article more than English does.

Here, la resolución refers to the resolution as the thing being measured. In Spanish, that sounds natural and standard. English might sometimes drop the article in similar contexts, but Spanish usually keeps it.

Also, resolución is a feminine singular noun, so it takes la:

• la resolución
• una resolución

Because resolución is a noun with grammatical gender, and in Spanish it is feminine.

Many nouns ending in -ción are feminine, for example:

• la resolución
• la información
• la opción
• la solución

So the article and any adjectives must agree with it in the feminine form.

Here en means in, and it is used to express the unit used for measurement.

So:

• medir algo en centímetros = to measure something in centimetres
• medir algo en metros = to measure something in metres
• medir algo en píxeles = to measure something in pixels

This is the normal preposition for saying what unit something is measured in.

Because resolution is normally expressed in pixels, not in just one pixel.

The singular is:

• píxel = pixel

The plural is:

• píxeles = pixels

So en píxeles means using pixels as the unit.

Píxel forms its plural as píxeles, which is the standard Spanish plural form.

Singular:

• el píxel

Plural:

• los píxeles

This follows a common pattern in Spanish where some words ending in -el form the plural with -eles.

They have accent marks because Spanish spelling shows where the stress falls when it does not follow the default stress rules.

• resolución has stress on the final syllable: re-so-lu-ción
• píxeles has stress on the first syllable: pí-xe-les

The written accents tell you how to pronounce them correctly.

In most of Spain, z is pronounced like the th in think.

So resolución in Spain sounds roughly like:

• re-so-lu-thyon

More carefully:

• re-so-lu-THYON

In much of Latin America, the z would usually sound more like an s. But since you asked about Spanish from Spain, the th sound is the expected one in most regions.

It follows a very common Spanish pattern:

• Verb + direct object + phrase of manner/unit

So here:

• Medimos = verb
• la resolución = direct object
• en píxeles = prepositional phrase telling you the unit used

This word order is completely natural in Spanish. You could change it in some contexts for emphasis, but this version is the most straightforward.

Yes, you could, but it changes the emphasis.

• Medimos la resolución en píxeles = neutral, standard word order
• La resolución la medimos en píxeles = puts extra focus on the resolution

That second version may sound like you are contrasting it with something else, for example:

• El tamaño lo medimos en centímetros, pero la resolución la medimos en píxeles.

So the original sentence is the more neutral choice.

Most likely, yes. In this kind of sentence, resolución usually refers to the resolution of an image, screen, display, or similar digital object.

In Spanish, resolución is the normal word for resolution in that technical sense, just as in English.

So the sentence sounds natural in a technology, photography, design, or computing context.
