LinkedIn Poll Limits: the Characters, Options and Durations That Bind
LinkedIn poll limits cap the question at 140 characters and each answer option at 30. A poll holds up to four options on desktop and Android, five on iOS, and runs for one day, three days, one week or two weeks. LinkedIn's help pages add that a poll cannot be edited once created or reopened once closed.

Where the 140-character wall sits
The hard wall in LinkedIn poll limits is text length. The question is capped at 140 characters, counting spaces, and each answer option at 30. That is the whole word limit in one breath: a question that fits in about twenty words and options that fit in about four. Anything you want to ask has to live inside that frame.
The caps change how you write. A question like "Which meeting format works better for a distributed team?" runs close to the ceiling once you count the spaces, so most creators end up rewriting twice. The answer options are tighter still: 30 characters holds "In person, twice a month" but not "In person twice a month, remote otherwise". The edit happens before posting, because the platform gives you no second pass.
In practice the character limit acts as an editor rather than an annoyance. It pushes the question toward a single decision and the options toward single nouns, which is exactly the shape a poll needs to collect clean numbers. LinkedIn says the same thing from its side: polls help you understand trends and opinions and can be a great conversation starter, and a conversation starter is short by design.
- A question at 140 characters: long enough for a real either-or, too short for background, nuance or a follow-up clause.
- An answer option at 30 characters: room for a word or three, and nothing more, so compound choices fall apart quickly.
- No separate headline field: the question is the headline, which is why the cap bites harder here than it first looks.
Four options or five: it depends on your screen
The option count is the strangest of the LinkedIn poll limits, because it is tied to the device you build on. On desktop and the Android app you can add up to four options. On the iOS app you can add up to five. The fifth slot is not a premium feature or a toggle; it simply exists on iPhones and iPads and nowhere else.
This matters at the moment of creation only. Once the poll is live, every voter sees the same set of choices whether they answer from a laptop, an Android phone or an iPhone. A poll built with five options on iOS shows five options to a desktop voter too. The reverse does not work: a four-option poll cannot be topped up later from an iPhone, because editing is off the table entirely.
One more mechanical point belongs here. Each member gets one vote on a poll at a time, and there is no multiple-answers switch in the LinkedIn poll form the way there is in a group chat poll. If a member removes their vote before the poll closes, they can vote again while it remains open, so the one-vote rule is firm while the poll runs but not permanent mid-run.
- Desktop: up to four options per poll.
- Android app: up to four options, matching desktop.
- iOS app: up to five options, the widest build the platform offers.
- After posting: the count is locked, and no device sees an extra slot.
How long a LinkedIn poll can run
Duration is the limit people trip over most often, because the form hides it behind a dropdown. A LinkedIn poll can run for one day, three days, one week or two weeks. Those are the only four values; there is no custom closing date and no way to type in nine days. One week is the default on desktop, so most polls you scroll past are running exactly that long.
The closing date does real work. While the poll runs, voters see the aggregate responses as percentages after they cast a vote. After it closes, anyone eligible to see the post can still see those percentages, so the numbers outlive the voting window even though no new answers land. The clock starts the moment you post and cannot be paused or stretched.
Plan around the shortest duration that suits the question. A two-week run sounds generous, but on a fast feed most of the answers arrive in the first day or two regardless, which is why the one-day and three-day settings exist for questions that will not survive that long anyway. The duration dropdown is the only timing control you get, so treat it as the whole schedule.
- One day: for time-anchored questions tied to an event or a launch day.
- Three days: the working-week compromise for professional audiences.
- One week: the default on desktop, and the safest general choice.
- Two weeks: the maximum, for slow-moving niche topics.
Why the limits are short on purpose
The purpose of these limitations shows in what the caps produce. LinkedIn's stated intent is that polls help you understand trends and opinions and start conversations. Everything about the form serves that: a 140-character question, 30-character options and a fixed run time make a poll answerable in two seconds, which is what keeps response rates high.
The limits also define what a poll is not. It is not a survey, not a discussion thread and not a place for open text; the long-form question belongs in a regular post or a proper survey tool. The platform's professional community policies push in the same direction, asking members to respond authentically to others' content and not to agree ahead of time to like or re-share each other's posts. A poll built inside the caps is part of that picture; a poll stretched to carry a campaign is not.
So the shortness is the feature. Strip the caps away and the poll becomes just another long post with numbers attached, and the quick aggregate view that makes polls shareable stops working. The limitations are the difference between a glance and a read, and LinkedIn has clearly chosen the glance.
- A short question lowers the effort of answering to near zero.
- Fewer options make the results easier to read at a glance.
- A fixed duration gives the poll a clear end and a clean final tally.
- One vote per member keeps the percentages meaningful.
Editing, reopening and other closed doors
Three doors stay shut the whole way through. A poll cannot be edited once it is created. It cannot be reopened once it closes. And there is no pause button between posting and closing, so a week means a full week. Any mistake in the question, the options or the duration costs the poll itself: you delete it and rebuild, and the early answers go with it.
That is why the drafting step matters more on LinkedIn than on tools with looser rules. Write the question and all four or five options in a separate note first, count the characters, check the duration against your calendar, and only then open the post form. The closed doors are the reason typos feel expensive here.
There is one reversal, and it belongs to the voter rather than the author. A member who removes their vote before the poll closes can vote again while it remains open. After the closing date passes, even that disappears: the votes are counted, the percentages freeze, and the post settles into being a record rather than a running tally.
- Editing after creation: not available, on any device.
- Reopening after the closing date: not available.
- Pausing mid-run: no such control exists.
- Removing your own vote before close: the one action that is reversible.
- Extending the duration: choose again from the four settings only by starting over.
The rules that sit on top of the limits
The character and duration caps are only half of what constrains a LinkedIn poll. On top of the mechanics sit the platform rules, and they are aimed squarely at numbers that arrive without people behind them. The user agreement prohibits bots and other unauthorized automated methods used to access the service or drive inauthentic engagement, and the platform states separately that it does not permit fake accounts or fake engagement, including tools or services that try to manipulate its content algorithms.
The commercial side is covered too. LinkedIn prohibits contest ads that offer incentives or compensation for actions artificially boosting engagement, which closes the door on prize-driven poll running on this platform. The professional community policies add a behavioural rule: respond authentically to others' content and do not agree ahead of time to like or re-share each other's posts. Misuse of features to inflate engagement is grounds for removal or limited distribution of the content itself.
For the author wondering what is actually visible, the mechanics make the picture fairly open. Poll authors can see the aggregate results as percentages and the number of votes per option, so a sudden flat surge on one option stands out against a natural spread. One vote per member is enforced at the account level, and voters see the percentages only after casting their own vote. Anyone planning to weight the outcome should assume the platform checks its own numbers, because the author can see them too.
- Contest or competition ads offering incentives or compensation for actions artificially boosting engagement: prohibited.
- Bots or other unauthorized automated methods used to access the service or drive inauthentic engagement: prohibited under the user agreement.
- Fake accounts or tools and services that try to manipulate the content algorithms: not permitted.
- Content designed to artificially increase engagement through misuse of features: liable to be removed or limited in distribution.

How to do it
-
Open the post form and pick poll
Start a post as usual and switch the format to poll. The question field enforces the 140-character cap as you type, so the limit is visible before you commit to any wording. Draft the question elsewhere first if it does not fit on the first try.
-
Write the question and every option to fit
The question gets 140 characters and each answer option gets 30, spaces included. Rewrite in nouns rather than sentences, cut qualifiers, and check that no option needs a second clause. There is no editing pass after posting, so the wording you publish is the wording that runs.
-
Choose four or five options on the right device
Desktop and the Android app allow up to four options; the iOS app allows up to five. If the question genuinely needs a fifth choice, build the poll on an iPhone or iPad. The count locks the moment the poll posts and applies to every voter from then on.
-
Set the duration and post
Pick one day, three days, one week or two weeks. One week is the default on desktop and suits most professional audiences. Once you post, the countdown starts and cannot be paused, extended or restarted, so the duration you choose is the one the poll keeps.
Common questions
Is there a character limit?
Yes. LinkedIn caps the poll question at 140 characters and each answer option at 30 characters, counting spaces. That makes a question roughly the length of a punchy headline, so the word limit forces you to choose what the poll is really about instead of burying it in a sentence. Options are even tighter, at about five words each.
Can a poll be edited?
No. LinkedIn states that a poll cannot be edited once it is created. The question, the options and the duration are locked at the moment you post, so a typo means deleting the poll and starting again. Draft the wording somewhere else first if the caps feel tight.
Can I reopen a poll after the closing date?
No. The help pages are direct about this: a poll cannot be reopened once it has closed. When the closing date passes, the results stay visible as percentages, but new answers stop counting. There is no extension, no second window and no restart for the same poll.
How long can a LinkedIn poll run?
Two weeks is the longest a LinkedIn poll can run. The platform offers four durations: one day, three days, one week or two weeks. One week is the default on desktop, and the countdown runs continuously from the moment you post, with no way to pause it in between.
What's the purpose of these limitations?
LinkedIn frames polls as a way to understand trends and opinions and to start conversations, and the limitations serve that purpose. Short questions, few options and fixed durations keep a poll light enough to answer in seconds. One vote per member and the ban on fake engagement protect the picture the results paint.
Is LinkedIn limiting desktop polls to 4 answers while mobile allows 5?
Yes, that split is real. On desktop and the Android app you can add up to four options, while the iOS app allows five. The choice exists only while you are building the poll; once it is live, every voter sees the same option count no matter which device they answer on.

These limits are LinkedIn's, and no setting changes them: a poll cannot be edited after creation, cannot be reopened once closed, cannot hold more options than your device allows, and its question and options cannot exceed the character caps. Removing a vote before closing is the one reversal a member controls.
X prohibits coordinating with or compensating others to inflate engagement metrics, and it names Polls among the features covered. The Pet Industry Business Awards name the consequence in their own contest: a business may be investigated, lose votes or be disqualified on reasonable evidence of purchased votes. No seller can stop an organiser from doing that.
Slido says it is alerted when an event gets an unusually high number of votes in a very short time, and Crowdsignal says its built-in measures detect patterns of potentially abusive voting. Ordinary participation arrives spread across the voting window, from different people at different moments. Nothing on this site is a method for getting a vote past a check, and a vote that a tool blocks does not count.
Organiser rules differ: the RSPCA Pet of the Year Awards allow extra votes through donations on their official mechanism, while OpenTable Australia treats a vote cast in exchange for money or a reward as null and void. Both are contest rules, not statutes, and whether payment is lawful where you live is a question for a lawyer. Orders are refused for any contest whose rules ban paid votes, and for political ballots.
Votes ordered for a poll that never appear on its count are refunded after the poll closes. A refund never covers an organiser's decision: Localsearch may void all votes for a disqualified nominee, and Mentimeter says a user whose access it cancels under its Acceptable Use Policy is owed no refund or compensation. No result is promised.
