The most common "cover image" requirement in Tally is the Company Logo. This appears at the top of your Sales Invoices, Purchase Orders, and Financial Statements.
Tally Pro users can adjust the cover height directly in the form customizer .
The optimal cover image size in Tally is not a single number but a function of target paper size and desired print quality. For standard A4 portrait reports, at 100 DPI offers the best balance of clarity, performance, and margin compliance. Users must avoid high-resolution images (>2MB) and always use the BMP format. Following these specifications ensures professional, full-coverage cover pages without cropping or distortion.
