The LinkedIn invitation limit applies to every member, free or Premium, and LinkedIn publishes no number for it, per week or per day. LinkedIn's help page on invitation restrictions says more invitations cannot be bought, then lists the reasons an account is stopped from sending them. The planner above quotes those reasons and the one figure people repeat, marked as reported rather than confirmed.
What LinkedIn counts against the limit
Volume is one reason, not the only one. LinkedIn names three ways to run into it:
many invitations sent in a short time
invitations that are often ignored, left pending, or marked as spam
too many invitations outstanding at once, the case with the longest wait
So the same count can be fine for one account and too many for another. Who you invite matters as much as how many, and a pile of unanswered invitations keeps counting after the week that sent them.
How to read your plan
The weekly figure is a share of the reported number. Your account's age and network can cut it, and nothing raises it above that number. The daily figure splits the week over the working days: read it as the most for one day, spread through the day, not a quota to reach.
Each step links to the limit it rests on, so you can see whether it stands on LinkedIn's own word or on a report. The planner covers invitations to connect, not invitations to follow a Page or attend an event.
What to do when the limit stops you
Stop sending invitations. Most restrictions lift on their own, and LinkedIn will not lift one on request. When you start again:
send fewer than before, spread across the week
withdraw invitations pending for weeks, one at a time, since LinkedIn has no bulk withdraw
invite people who share connections or context with you, and add a note only when it says why you are writing
The LinkedIn weekly connection limit, with sources covers where the weekly figure came from. In Oneprofile, connection requests always keep a daily and a weekly limit you set, and the Chrome extension does each request in your own browser, the way you would click it yourself.
