Check KDP metadata, cover dimensions, margins, royalties, PDFs, checklists, and saved book projects. KDP Launch Check helps self-publishers review their books before publishing through Kindle Direct Publishing. Use the extension to check book metadata, calculate paperback cover dimensions, estimate margins and royalties, inspect basic PDF properties, complete a publishing checklist, and save book projects for later. FEATURES • Metadata preflight Review your book title, subtitle, author name, description, and keyword phrases. The extension highlights common metadata issues and wasted keyword space. • Publishing checklist Track important steps before submitting your book, including metadata, categories, pricing, manuscript review, cover review, and publishing settings. • Cover and spine calculator Calculate paperback spine width, full-wrap cover dimensions, and recommended 300-DPI pixel dimensions using trim size, page count, ink, and paper selections. • Margin and gutter calculator Estimate minimum inside, outside, top, and bottom margins based on page count and bleed settings. • Royalty and profit estimates Estimate printing cost, royalty per sale, profit margin, break-even price, target pricing, and projected monthly earnings. • Basic PDF inspection Check an interior PDF for page count, page dimensions, inconsistent page sizes, possible two-page spreads, encryption, and other common setup issues. • Saved book projects Save book information locally, restore drafts, and import or export project backups as JSON files. • Side panel and full-page modes Use KDP Launch Check beside your publishing dashboard in Chrome’s side panel, or open it in a full browser tab for a larger workspace.
