Claude limit habits — the one-page, no-install list

Seven habits that stop Claude's limit from running out, straight from Anthropic's own help pages. Nothing to install. Only the attachment costs have published numbers.

Nothing officially ranks first. Your limit goes to whatever each message drags in — the whole chat so far, every attached page, and every switch you left on. Seven habits, all inside the chat window, nothing to install. Every line below comes from Anthropic’s own help pages, checked 2026-09-03. Only the attachment costs have numbers; the rest is marked official, size not published.

Anthropic’s factors — the official list of what your limit goes to, in no particular order: “Message length, File attachment size, Current conversation length, Tool usage (e.g., Research, web search), Model choice, Effort level, Artifact creation and usage.” Anthropic’s usage page, checked 2026-09-03. No page says which one is biggest. These are the factors, not the seven habits below.

0. Look here first

Settings > Usage. Two bars: your five-hour session and your week. The session bar resets every five hours. The weekly bar resets at a fixed time assigned to your account. Web, desktop and Claude Code all count into the same bars. (official)

Start and end the chat on purpose

1. One task per chat. When the task changes, start a new conversation. If you need the context, ask for a short summary and paste it into the new chat. Anthropic’s line: “Try starting a new conversation if you’re approaching your usage limit in a longer chat.” The summary step is widely recommended; Anthropic only states the new-chat half. (official, size not published)

2. Everything in the first message. Goal, format, constraints, and every related question in one message. Anthropic’s words: “Batch similar requests in one message.” (official, size not published)

Attachments — the one cost with real numbers

3. Paste the part, not the file. Select the paragraph you need, copy, paste. Nothing to install.

4. Crop the screenshot before you drop it in. The screenshot tool on your OS already does this.

5. Reused files go in a Project, once. Open a Project and upload the file there instead of attaching it in every chat. “When you upload documents to a project, they’re cached for future use,” and “only new/uncached portions count against your limits.” Projects load “only relevant content into the context window.” (official, size not published)

The numbers — all official, Anthropic API docs, checked 2026-09-03:

PDF: “Each page typically uses 1,500–3,000 tokens per page depending on content density,” plus an image cost on top, “because each page is converted into an image.”
Image: ⌈width/28⌉ × ⌈height/28⌉ tokens. A 200×200 crop is 64. A 1000×1000 image is 1,296. A 1920×1080 screenshot is 1,560–2,691.
Word, spreadsheet, plain text: no image part. “For non-PDF documents: Claude extracts text only from these files.”

Switches — set once, they stay set

6. Effort down, lighter model for routine work. Pick the model from the model picker. The effort picker only appears on the newest models; set it to Low or Medium. Anthropic: “Low and Medium work well for routine tasks and stretch your usage further.” Note: “Thinking cannot be turned off in Claude when using Claude Fable 5.1 or Claude Opus 5” — on those two, effort is the lever you have. How much lighter a lighter model is on a subscription is not published. (official, size not published)

7. Search tools off unless that chat needs them. Open the “Search and tools” settings. Anthropic’s wording: “Disable web search, Research, and MCP connectors from your ‘Search and tools’ settings when they’re not needed for specific conversations.” And when you want a file made, plan it in chat first and generate it once at the end — “creating files will use more of your limit compared to normal chats with Claude.” (official, size not published)
