The recipient block is locked to the DIN 5008 field of 45 × 85 mm, with fold marks at 105 and 210 mm. Print at actual size and test-fold a copy against your envelope before sending; window positions vary between envelope suppliers.

FAQ
Questions, answered.
Is Letter Studio really free?
Yes. Every template, the editor and PDF export are free to use, with no watermark on your documents.
How long does it take to make a letter?
Most letters take under five minutes: pick a template, replace the sample names and details, add your logo and signature, and export a print-ready PDF.
What makes it better than Word or Google Docs for letters?
Word processors are built for continuous text, so logos, margins and address blocks drift as you edit. Letter Studio locks your letterhead structure in place, so every letter stays balanced and ready to print.
Will the address fit a window envelope?
The A4 layout uses a DIN 5008-style address field and fold marks. Print at actual size and test a copy in your own envelope; paper size, printer scaling and window positions affect the fit.
Can I create multi-page letters and contracts?
Yes. Add continuation pages at any time. Later pages switch to a clean running header with Page X of Y numbering.
Which paper sizes and file formats are supported?
ISO A4 and US Letter. Download a high-resolution PDF with sharp text and logos, or print directly from your browser.
Can I add my logo, signature and company stamp?
Yes. Upload a logo, draw or upload a signature, and add a circular seal or rectangular company stamp with your own text and ink colour.
