“Weigh in” in a sentence most often means “give an opinion,” as in: “Please weigh in on the plan by Friday.”
“Weigh in” looks simple, yet it trips people up. In class writing, emails, and comment threads, you’ll see it used as a verb phrase: someone weighs in with a view. In sports writing, it can mean stepping on the scale before a bout. Add the hyphenated noun “weigh-in,” and the spelling changes again.
If you searched weigh in a sentence, you’re likely after one thing: a sentence that’s correct, sounds natural, and fits the meaning you want. This page gives you ready-to-copy models, plus the small grammar choices that make the line feel smooth.
Weigh In A Sentence with tone and timing
Start by picking the meaning you want, then match it to the setting. In daily writing, “weigh in” almost always means sharing a view. It often pairs with on (“weigh in on the topic”) or with (“weigh in with a suggestion”).
In sports contexts, “weigh in” can mean being weighed before an event. That version often appears with a number (“weighed in at 145 pounds”). If you’re writing about an event itself, the noun form is common: “the weigh-in.”
| Common use | What it means | Sample sentence |
|---|---|---|
| Opinion (verb) | Share a view or judgment | Before we finalize the schedule, I’d like you to weigh in on the dates. |
| Opinion (verb + with) | Add a suggestion or detail | Jordan weighed in with a short list of edits for the intro. |
| Opinion (verb + when) | Offer input at a set time | If you can’t meet, weigh in by email tonight. |
| Sports (verb) | Be weighed before competing | The fighter weighed in at 154 pounds and smiled for the cameras. |
| Weight total (verb + at) | Have a stated weight | The suitcase weighed in at 22 kilograms, so we shifted a book to the carry-on. |
| Event (noun, hyphen) | The official weighing event | Fans lined up early for the weigh-in at the arena. |
| Figurative “count” | Have influence in a decision | Cost should weigh in when we compare the two plans. |
| Legal or formal writing | Give an official statement | The court may weigh in on the dispute later this year. |
Dictionary entries help you confirm which sense fits your line. The Merriam-Webster definition of weigh in shows both the verb and noun uses, including sample sentences.
What weigh in means in plain English
In normal conversation, “weigh in” means “give your take.” It’s the phrase you use when you want someone’s input, or when someone offers it without being asked. You can ask for it (“Can you weigh in?”) or report it (“She weighed in during the meeting”).
In sports, it can mean “step on the scale,” often right before competition. You’ll see “weigh in at” tied to a number. In non-sports writing, “weigh in at” also shows up for objects, animals, and totals, like luggage weight or package weight.
Then there’s “weigh-in” with a hyphen. That’s a noun. It names the event, the ritual, or the moment when people get weighed. It can also be used more loosely to mean “input” as a noun (“Thanks for your weigh-in”), though many editors stick to “input” in that case.
When to use weigh in vs weigh-in
This is the most common spelling snag. Use weigh in (two words) when it acts like a verb phrase. You can change its tense: weigh in, weighs in, weighed in, weighing in.
Use weigh-in (hyphenated) when you mean the noun. Nouns can take an article (“a weigh-in”), a plural (“two weigh-ins”), or adjectives (“a late-night weigh-in”).
Quick checks that usually work
- If you can replace it with “comment,” use weigh in: “I’ll weigh in after lunch.”
- If you can replace it with “event” or “official weighing,” use weigh-in: “The weigh-in starts at 6.”
- If you see “at” plus a number, you’re almost always in verb territory: “She weighed in at 130.”
Grammar patterns that make the sentence sound natural
Most awkward lines fail for one of two reasons: the preposition is off, or the sentence doesn’t show who is speaking and what they’re speaking about. The fix is usually small.
Pattern 1: Weigh in on + topic
This is the cleanest pattern for opinions. It’s direct and works in school writing, emails, and reports.
- Please weigh in on the rubric before I print it.
- Several students weighed in on the reading list during class.
- She weighed in on the budget with two clear questions.
Pattern 2: Weigh in with + suggestion
Use this when you want to point to the thing that was added: a tip, a fix, a detail, a reason.
- He weighed in with a calmer tone after the debate got tense.
- My mentor weighed in with a line I could use in the introduction.
- Two editors weighed in with changes to the headline.
Pattern 3: Weigh in at + number
This is the weight sense. It’s common in sports writing and also shows up with objects.
- The boxer weighed in at 147 pounds on Friday morning.
- Our carry-on weighed in at 9.5 kilograms, so we removed a charger.
- The puppy weighed in at just 3 pounds at the vet.
Cambridge’s entry focuses on the “be weighed” sense, which can help when you’re writing about numbers and official measurements. See the Cambridge Dictionary meaning of weigh in for that usage.
Ways to fit weigh in into different writing styles
“Weigh in” works in casual writing and formal writing, but the surrounding words should match your tone. In a text message, you can keep it short. In a report, name the topic and the timing so your sentence feels complete.
Casual lines

Lines that sound calm and fair
Sometimes you want input without sounding pushy. A small tweak can shift the vibe: use a soft opener, name the topic, then give a time window. In a memo, this keeps the sentence tidy and invites a response.
- When you have a minute, weigh in on the order of the slides.
- If you see any gaps, weigh in with a quick fix and I’ll patch it.

Common mix-ups and clean fixes
Some errors repeat across student writing and office writing. Most come from confusing “weigh in” with “weight,” mixing up the hyphen, or using the phrase without a clear topic. The table below gives fast repairs without rewriting the whole paragraph.
| Slip | Why it reads off | Clean fix |
|---|---|---|
| “I will weight in.” | “Weight” is a noun; the verb is “weigh.” | I will weigh in. |
| “The weigh in was at 6.” | The noun form takes a hyphen. | The weigh-in was at 6. |
| “Weighed in about the idea.” | “On” is the usual preposition for opinions. | Weighed in on the idea. |
| “Weigh in of the plan.” | “Of” doesn’t fit this verb phrase. | Weigh in on the plan. |
| “Weighing in the topic…” | That pattern sounds like measuring weight, not sharing a view. | Weighing in on the topic… |
| “They weigh-in on it.” | Hyphen breaks the verb phrase. | They weigh in on it. |
| “My weigh in is…” | As a noun meaning “input,” it can work, yet many editors prefer “take” or “input.” | My take is… |
| “It weighed in the decision.” | Missing a connector that shows influence. | It weighed in on the decision. |
How to write your own weigh in sentence in 30 seconds
If you want a line that doesn’t sound copied, build it with three slots: who, verb form, topic or detail. Then add a time cue if the reader needs it.
- Pick the meaning. Opinion? Weight number? Event noun?
- Choose the right form. “Weigh in” (verb) or “weigh-in” (noun).
- Add the connector. Use “on” for topics, “with” for additions, “at” for numbers.
- Check the tense. Present for general truths, past for what happened, “can” for permission.
- Read it out loud once. If it trips your tongue, shorten the ending.
Here are quick templates you can adapt without overthinking:
- [Name] weighed in on [topic] during [place/time].
- Please weigh in with [detail] so we can finish [task].
- The [person/thing] weighed in at [number] on [date].
- The weigh-in started at [time], and the crowd stayed quiet.
Practice prompts for students and writers
If your assignment asks you to use “weigh in,” the grader often wants two things: correct grammar and a clear meaning. Try one prompt, write one line, then check it against the patterns above.
Opinion prompts
- Ask a classmate to share input on a group project.
- Report what an author says about a topic in an essay.
- Write an email line asking for feedback before a deadline.
Weight prompts
- Write a sports recap line using “weighed in at” with a number.
- Write a travel line about luggage weight at check-in.
- Write a science notebook line about measuring a sample.
Self-check questions
- Did you use “weigh” as the verb, not “weight”?
- If it’s an opinion, did you use “on” or “with” in a clean way?
- If it’s the event, did you hyphenate “weigh-in”?
- Can someone who hasn’t read your notes still get the meaning?
Mini reference: tense forms you’ll see most
Verb phrases change with tense, so it helps to keep the main forms in your head. Present: “I weigh in.” Past: “I weighed in.” Ongoing: “I’m weighing in.” Third-person present: “She weighs in.” If you’re writing a neutral report, “weighed in” often reads smooth because it tells the reader the input already happened.
If you’re writing a headline or a caption, you can drop extra words and still stay grammatical: “Coach weighs in on roster move.” In body text, add the topic and the timing so the sentence doesn’t feel clipped.
