Reasons and solutions for incomplete display of Word formulas

Key points of this article

The top and bottom of the formula are cut off. Usually the paragraph spacing is set to a fixed value, and it can be changed to single or multiple spacing.
The formulas are not fully displayed in the table or text box. Most of the time, the row height or box height is fixed. Please release the restrictions and check again.
Formulas are higher than text, often because fractions, radicals, and superscripts and subscripts support high line heights. This can be alleviated by unifying line spacing and simplifying formula writing.
If the entire formula becomes a code or a blank box, first check the field code display switch and formula object type, and then consider the font problem.

After inserting formulas in Word, many people find that the upper or lower half of the formula is missing, or the formula is much higher than the text next to it, and the upper and lower lines are almost stuck together. Some documents were received from others, and the formulas that were originally displayed normally became incomplete after changing to another computer or changing the paragraphs.

This type of problem looks like a typesetting error, but in fact it is mostly a display-level failure: problems with line spacing, table row height, formula object type or font, rather than incorrect page margins or style settings. First match the symptoms and causes, and then check them in order from easy to difficult, and you can usually locate them quickly.

This article is for readers who have encountered formulas that are truncated, obscured, misplaced, or not displayed at all. After reading this, you will be able to determine which situation you belong to, know what to change in each situation, and know how to reduce the chance of it happening again in the future.

The formula is not fully displayed, what should I do? One sentence conclusion

In most cases, the problem can often be solved by first changing the line spacing of the paragraph where the formula is located from a fixed value to single or multiple line spacing, and then checking whether the formula is placed in a table or text box with a fixed height. The table below can help you find your seat.

your situation	Recommended practices	reason
The formula is cut off above and below, and the text looks normal	Change paragraph spacing to single or multiple spacing	When the fixed line spacing is less than the height of the formula, the excess part will be cropped.
Formulas are not fully displayed in table cells	Change the row height to a type that adjusts with the content	Fixed row height limits the display range of cell content
The formula is higher than the text next to it	Unify paragraph spacing and simplify formula writing	Fractions, radicals, and superscripts and subscripts will raise the line
The entire formula turns into code or a blank box	Check field code display and formula object types	Mismatch in display settings or object types can change how formulas are rendered
The same formula works fine on other computers	Check if math font is complete	Symbols will be replaced when the font is missing, and the size and position may be abnormal.

First determine what kind of problem it is

Before making any modifications, you can use the table below to confirm the causes of the symptoms. Each item can be checked in a few minutes on your own computer.

symptoms	Common causes	How to confirm
The upper or lower half of the formula is cut off	Paragraph line spacing is a fixed value, and the value is smaller than the formula height	Open the paragraph settings and check whether the line spacing type is fixed value
Formulas are not fully displayed in the table	The height of the cell or row is fixed	Select the table row and check whether the row height is a fixed value
The formula is taller than the text, and the line spacing is sometimes large and sometimes small.	Fractions, radicals, and matrices support high row heights; formulas in the same paragraph are not written uniformly	Select the same paragraph and compare the height and alignment of each formula
Formulas appear as braces, commands, or empty boxes	The formula object is not loaded correctly, or field code display is turned on	Press Alt+F9 to switch field codes on Windows and compare the before and after effects
The formula works fine on one computer, but there are missing symbols or boxes on the other computer.	Math fonts are missing or font substitution occurs	Open the file on another computer and observe whether the symbols are abnormal.
Normal on screen, cut after printing or exporting PDF	Trimming due to centering, page breaks, or page boundaries	Print preview to check whether the formula is on edge or spreads across pages

Check and repair item by item

Deal with them separately according to the following reasons. If several symptoms occur at the same time, it is recommended to start from the first part and review it again after each correction.

1. The line spacing is a fixed value, resulting in cropping

Select the paragraph where the formula is located, open the paragraph settings, and check the line spacing type.
If it is a fixed value, change it to single or multiple spacing, and increase the value appropriately.
Check whether other paragraphs in the same document also have fixed line spacing, and adjust them uniformly if necessary.

2. The height of the table or text box is limited

Select the table row containing the formula and check whether the row height is fixed.
Change the row height to a type that can automatically adjust with the content, so that the cell height changes with the formula.
If the formula is in a text box, enlarge the height of the text box or cancel the fixed height, and then confirm that the text is not clipped.

3. The formula is higher than the text or the line spacing is large or small.

Distinguish between inline formulas and formulas on separate lines. Small formulas should be kept within the main text line, and large formulas on separate lines are recommended to be placed in independent paragraphs.
For simple fractions, you can use linear (one line) writing to reduce stretching in the up and down directions.
Unify the line spacing of the same paragraph to avoid mixing multiple line spacings in one paragraph.
Select the formula and check whether its alignment is consistent with the text baseline.

4. Formulas are not displayed or displayed as codes

On Windows, press Alt+F9 to toggle field code display and see if the content changes to code. Press again to switch back to normal view.
If the formula is an old object inserted using other formula editing components, only placeholders or blanks may be displayed on computers that do not have corresponding components. You can re-enter the formula on a computer that can display it normally.
If there is text code such as \frac, it means the formula has not been converted. You can re-enter it using Word's formula feature, or enter it in linear format and then convert it to a formal formula.
If there is no suitable Word version, you can use UniDoc web editor (app.unidoc.top) to open the Word file and check whether the formulas can be displayed normally.

5. Abnormal symbols caused by missing fonts

Check whether the formula symbols are displayed as boxes on the computer with the problem, or the fonts are obviously inconsistent with other places.
Math fonts such as Cambria Math are usually installed with Office. If it is missing, you can repair the Office installation first and then reopen the file to check.
If it cannot be repaired, re-enter the formula, use the math font that comes with the system, and confirm again on another computer.

How to avoid it happening again next time

Before inserting formulas, set paragraph line spacing to single or multiple times. Do not use fixed line spacing to save space.
When placing the formula into the table, select a row height type that can be adjusted with the content, and do a print preview after writing.
Try to use the same insertion method for formulas in the same document to avoid mixing old formula objects, pictures and text codes.
Before handing the file over to others, open it in the same version of Word to check; when transferring it across computers, make sure the other party also has the fonts used in the document.
For files that need to be saved or distributed for a long time, check the pagination and margins before exporting to PDF to avoid formulas that cross pages or overlap.

❓ Frequently Asked Questions (FAQ)

1. The formula works fine on other people’s computers but not on mine. What should I do?

Check the domain code display and font first, and then check whether Office is completely installed. If the formula is an old formula object, you can re-enter the formula on a computer that can display it normally, and then save the file.

2. The formula displays normally on the screen, but is cut off after exporting to PDF. Why?

The layout and pagination positions of the screen view and the exported page may be different. First do a print preview to see if the formula is welted or spread across pages, then adjust the paragraph position or page margins and re-export.

3. After modifying the line spacing, the formula is still higher than the text. What else can be done?

Line spacing can only unify the spacing between rows, but cannot eliminate the height of the formula itself. You can change complex vertical fractions to linear writing, or put large formulas in a separate paragraph to reduce the impact on the text lines.

4. Can saving the document in a new format solve the problem of incomplete formula display?

The save-as format itself usually cannot fix display errors. A more effective approach is to check the line spacing, line height, and formula object type first, and then modify them after confirming the cause of the problem.

📝 Summary

Word formulas are not fully displayed, mostly due to fixed line spacing, limited table row height, mismatched formula object types, or missing fonts. Compare the symptoms with the table to determine the cause. First change the paragraph spacing and line height, and then check the field code and font. Most problems can be solved smoothly.
