Why does my document look different on someone else's computer?
Fonts, versions and paper size, in that order. Why the layout moves, and the one thing to do when it absolutely must not.

Short answer
Usually fonts. A document records which font to use, not the font itself, so a machine without it substitutes another with different letter widths and everything reflows. Next most likely is a different version or a different program opening the file, and third is paper size — A4 against US Letter shifts every page break. If the layout matters, send a PDF, which carries the fonts and the layout with it.
Step by step
- Send a PDF when the layout matters.This is the answer, and everything else is a workaround. A PDF embeds the fonts and fixes the layout, so it looks the same everywhere and cannot be accidentally edited. Send the editable file only when the recipient needs to edit it.
- Understand the font substitution.Your document says "use this font". A machine that does not have it picks something else, and different fonts have different letter widths, line heights and spacing. Text reflows, line breaks move, and a carefully placed page break lands in the wrong place.
- Stick to fonts that exist everywhere.If the file must stay editable, use fonts that ship with the operating systems and office suites your recipients use. A downloaded or purchased font will not travel with the document unless it is embedded, and licensing sometimes prevents embedding.
- Embed the fonts where the program allows it.Word processors offer a save option to embed fonts in the file. It increases the file size and solves the problem for recipients using the same program. It does not help if they open it in a different program.
- Check the paper size.A4 is standard in the UK and Letter in North America. They are different sizes, so a document laid out for one repaginates on the other. Set the paper size explicitly rather than accepting the printer default.
- Consider the program, not just the version.A Word document opened in a free office suite, in a web version, or on a phone will render approximately rather than exactly. Complex layouts, text boxes, tracked changes and equations are where the differences show first.
- Simplify the layout if it must stay editable.Styles rather than manual formatting, tables rather than tabs and spaces, and as few text boxes and floating images as you can manage. Documents built with styles survive translation between programs far better.
- Test before it matters.Send it to yourself and open it on a phone, or in a web version of the office suite. Two minutes, and it catches most of these before a client or a printer sees it.
If it doesn't work
Layout shifted and page count changed
Cause: Font substitution or paper size — Fix: Send a PDF. If it must be editable, switch to a widely available font and set the paper size explicitly.
Boxes, images or diagrams moved
Cause: Floating objects anchored to text that reflowed, or unsupported features in the other program — Fix: Anchor images in line with the text rather than floating where you can, and simplify. For a fixed design, PDF.
Special characters show as squares or question marks
Cause: The substituted font lacks those characters — Fix: Use a font with wide coverage, or send a PDF. Common with symbols, mathematical characters and non-Latin scripts.
Recipient says the file will not open at all
Cause: An old program that predates the format, or a file saved in a newer format than they have — Fix: Save in an older or more universal format, or send a PDF. Free viewers exist for every mainstream office format.
Printed output does not match the screen
Cause: Printer margins, scaling, or the driver substituting fonts — Fix: Print from a PDF rather than the source document, and check the print dialogue is not scaling to fit.
Questions people ask
Does PDF always look identical?
Very close to always, provided the fonts were embedded when it was created, which modern tools do by default. It is the closest thing to a guarantee available.
Should I send a Word file or a PDF?
PDF unless they need to edit it. It preserves the layout, is harder to alter accidentally, and opens on anything. Send both if they may want to edit and you care about the appearance.
Why does my document look different on my own phone?
The phone version of an office app is a different renderer with different fonts available. It is the same substitution problem in miniature, and it is a useful quick test.
