increase the max chat window width. Often I ask a model to summarise what has changed in a before/after table.
Which results in a large table for quick review. But the max width of the chat window is quite limited. I’m on 49 inch ultrawide (5120x1440) so I need to scroll a lot horizontal inside those tables even though I have all this screen real estate around the chat input window/messages doing nothing..
Same issue on 4K – content should use full panel width
I’m on Windows with a 4K monitor. Even when I resize the conversation panel to more than half of the screen, the actual message content stays in a narrow column in the middle with large empty strips on the left and right. Wide content (tables, code) still forces horizontal scrolling.
It would be great if the chat content could use the full width of the panel (or if there was a setting for max content width). Right now a lot of space is wasted on large displays.
Can we have an update on this? It’s still abn issue, even more so now that the chat often replies with a table that usually doesn’t fit the width of the chat tab
Yes, please remove the fixed max width of the chat pane. It’s very annoying when tables are displayed in the chat window that would fit just fine into the pane but must now be scrolled horizontally to view everything.
Kind of works… but content inside tables stops mid section, so it does not use the available width. MD tables are one of the main reasons you want unrestricted width of chat window, since I’m asking agents all day to compare code changes.
Both the Anthropic and OpenAI VS Code plugins have better UI/UX for chatting / agent use. Take a look at your competitors I would say. I mainly now use their plugins / paid plans inside Cursor. Since those plugins became so good, I could just as well start to use VS Code itself and move away from Cursor altogether, since UX/UI is quite important for me.
Should be top priority for folks at Cursor too, it’s only thing where you can still make a distinction from big AI companies.
To not sound like old grumpy coder some compliments to end my feedback: The UI editor is a really neat feature saving lots of time for UI work. Those kind of things would keep me going back to Cursor.
I had the same problem on my UW monitor, so I was always carrying a patch in Custom UI Style extension
you could add to your "custom-ui-style.stylesheet": {
"div:has(> .composer-human-ai-pair-container), div:has(> div > .composer-human-ai-pair-container)": "max-width: 95% !important; width: 100% !important; margin: 0 auto !important;",
"div:has(> div > .aislash-editor-input), div:has(> div > div > .aislash-editor-input)": "max-width: 95% !important; width: 100% !important; margin: 0 auto !important;",
".composer-human-ai-pair-container, .composer-rendered-message, .markdown-root, .composer-human-message-container, .composer-human-message": "max-width: none !important; width: 100% !important;",
It can break with future updates, and you might want to tweak to your liking. But at least it’s better than this wasted space on both sides since day 1.
I’m glad Cursor acknowledged this with the next version.
Thanks for flagging this. We did ship wider chat/composer layout work (including on Nightly first), and some people still hit limits, especially with wide markdown tables — and Cursor 3 may behave differently from the older layout.
To tell whether you’re seeing the same issue as earlier in the thread or something Cursor 3–specific, could you share:
Cursor version and confirm you’re on the Cursor 3 / new UI
A screenshot showing the chat panel with the empty side margins or horizontal scroll
Whether the chat sidebar can be dragged wider or feels “stuck”
If it looks like a bug, a Request ID from a session where you reproduced it helps a lot.
