Size of Titles in Headline Boxes
 

I have set the font size in both the Headline Boxes (text and link) to 1.5em, but for they come out differently.

The About page (permanent) and Recent Pages have a smaller sized title, and the home page (with the latest post) plus categories and archives have a larger title.

How can I get them all the same?

Thanks in advance.

Remove the 1.5em from the Home Page style (HEADLINE Box: Links). On the home page the 1.5em of the <h2> tag and the 1.5em of the enclosed <a> tag are adding up. On the single post pages there is no enclosed <a> so it's not adding up there.

I use these settings

padding: 0;
margin: 0;
font-family: arial, verdana;
font-size: 150%;

inside

HEADLINE Box: Text
HEADLINE Box: Links
HEADLINE Box: Links: Hover

The result is headline size in single post is much smaller than multipost.

What do you mean add-up effect?

Even I reset to default settings,

Its headline (size and bold hightlight) in the single page is not look the same with headline in the multipost.

Remove

font-size: 150%;

from both

HEADLINE Box: Links

and

HEADLINE Box: Links: Hover

The HEADLINE Box: Text will cover the size for all three. Use the HEADLINE BOX: Links.. styles for color and text-decoration only
