Featured Images, Excerpts, and Archive Rhythm

The archive list is where most readers first encounter your blog. They scan it quickly: do the titles interest them? Does the site feel dense or spacious? Do the excerpts give enough context to decide whether to click? These are perceptual decisions that happen in a few seconds. How a theme handles featured images and excerpts shapes that first impression significantly.

Featured Images in Archive Views

Blaskan displays featured images in the archive list when a post has one set. The image appears above the post title at the top of each entry.

The display dimensions are determined by the image size WordPress generates. For archive listings, Blaskan uses a landscape crop. The exact pixel dimensions depend on your WordPress media settings, but the image fills the content column width at its display size.

When featured images are absent: If a post has no featured image, the entry in the archive renders without an image placeholder. The title, byline, excerpt, and read-more link appear at the top of the entry space. No empty box or broken image element appears. The entry is visually shorter than an entry with an image.

This is an important behavior. A gap between an image and no image in a post list creates visual inconsistency. Some themes handle this by requiring images or by generating a placeholder. Blaskan chooses not to penalize posts without images by inserting empty space. The result is that an archive with a mix of image and non-image posts has an uneven rhythm, but it is honest about the content rather than manufacturing false uniformity.

The practical implication: If consistent archive presentation matters to you, the simplest solution is to set a featured image on every post. This keeps the list uniform. If you publish content where images are not appropriate (a text-focused writing blog, for example), remove featured images entirely across all posts and the archive settles into a clean text-only list.

Image Upload Recommendations

For featured images that appear in archives:

• Minimum 1200px wide to avoid upscaling on standard displays
• Minimum 1600px wide if you want to serve high-density displays well
• Landscape aspect ratio (3:2, 16:9, or similar) to match what the archive crop expects
• JPG format for photographic content

Very tall portrait images in archive lists create inconsistent entry heights and make the list harder to scan. If you have portrait images, a wider crop is usually cleaner.

Excerpts: Manual vs. Automatic

WordPress generates an automatic excerpt by pulling the first 55 words of the post content (by default). It strips HTML and ends the excerpt at a word boundary, appending a read-more indicator.

Manual excerpts are set in the Excerpt field in the post editor (under the content area; may need to be enabled in Screen Options). When a manual excerpt is set, it replaces the auto-generated one in archive displays.

Why manual excerpts work better:

Auto-generated excerpts are unpredictable in two specific ways. First, they may include text from the middle of an introductory thought, leaving the excerpt mid-sentence even though the full sentence appears just after the 55-word cut. Second, they do not account for content structure. If the first 55 words of a post are a pull quote, an image caption, or a blockquote, that is what appears as the excerpt, which is often not what you want.

Manual excerpts let you write specifically for the archive context. A well-written excerpt summarizes the subject, establishes voice, and gives the reader a clear reason to click through. It functions differently from the opening of the article itself.

Excerpt length: 30 to 50 words works well in Blaskan's archive layout. This range is short enough to maintain list density, long enough to establish context. Some publishing workflows use shorter excerpts (a single sentence) for high-frequency post volumes. Longer excerpts of 80 or more words start to feel like article previews rather than list items.

Archive Rhythm and Post Length

The combination of featured images, excerpt length, and whether category labels are shown determines how much vertical space each post entry occupies in the archive.

A typical entry with a featured image, a 40-word excerpt, and a category label takes up substantially more screen space than a text-only entry. On a monitor, five or six image-bearing posts may fill two or three screens. On a phone, each entry may occupy most of the viewport.

This is not inherently a problem, but it shapes how readers experience the archive. A dense list of short text entries encourages scanning. A spacious list of image-bearing entries encourages slower, more considered reading.

Choosing deliberately is the point. Decide what the reading experience of your archive should be, then configure featured image use and excerpt length to match that intention.

What Breaks Archive Rhythm

Several content practices create awkward archive output:

• Inconsistent excerpt lengths that make some entries very tall and others very short within the same list
• Posts where the auto excerpt catches an image caption or a block quote introduction
• Mixed use of featured images on some posts but not others
• Very long post titles (over 80 characters) that wrap across multiple lines in the archive, shifting the visual weight of those entries

None of these are catastrophic. They are worth noticing and addressing through consistent content practices or by setting manual excerpts on existing posts.
