Can't change the font of a MathType equation number

You have tried to change the font of MathType's equation numbers from Calibri 11 to Times New Roman 12, clicking every button and selecting every dropdown. You've done everything you can think of, but nothing works, including the "Format Equation Numbers" dialog.

Equation numbers that are inserted by MathType are simply text, so they can be styled like any other text in Word. There's more to it than that though; read on…

  1. Even though MathType does not control the font Word uses for equation numbers, MathType does provide a style for this, and by controlling the definition of this style, you can control which font and font styles Word will use for equation numbers. This style is named MTDisplayEquation. This style is not included by default on Word's Style Gallery, nor does it exist before you insert a display equation into the current document.
  2. If you're using a Mac, proceed to the next step. On Windows, to find the MTDisplayEquation style and modify it click the dialog launcher at the lower corner of the Styles group of the Home tab: dialog launcher. When you do that, you'll see the MTDisplayEquation style near the top of the Styles panel (screen shot on left below). If you hover the mouse over that style, you can see the complete definition for that style. (You may also see the MTEquationSection style; we recommend leaving that one alone.) Proceed to step 4.
  3. If you're using Word 2011 on Mac, click the Manage styles icon on Word's Home tab: Manage Styles icon in Word 2011. If you're using Word 2016 on Mac, click the Styles Pane button on Word's Home tab: Styles Pane button in Word 2016. When you do that, you'll see the MTDisplayEquation style near the top of the Styles panel (screen shot on the right below). If you hover the mouse over that style, you can see the complete definition for that style.

  4. Click the downward-pointing triangle to the right of the MTDisplayEquation label, then Modify ("Modify Style..." on the Mac), and you'll have an opportunity to change the style's definition. You can also choose whether you want to apply bold, italic, or underline styling to the equation numbers within your document.
  5. Note these changes will affect only the equation numbers. The equation itself is not affected, nor are equation references.
