Place Slam within Wiescher’s work
On his own site, Gert Wiescher describes Slam as an offshoot of Supra. The publisher’s Slam Rounded account identifies a slab serif drawn with body copy in mind, with Normal and Rounded versions and oblique companions. Keep those branch names attached to proofs: a result labeled only Slam loses a meaningful design choice.
Compare the two branches in a reading specimen
Build a small field-notes page with a title, a paragraph and a caption. Hold the column width and text size steady while changing between Normal and Rounded. Note whether the terminal treatment changes the page’s overall texture or the distinction between the title and body. Use an actual companion oblique for emphasis rather than applying an artificial slant. Repeat the comparison with the longest caption, where a tight line can expose a choice hidden by a large title.
Make a small-cap and numeral control sheet
Wiescher specifically calls out small capitals and different numeral forms. Prepare a label with an abbreviation, a date, a price and a short column of amounts. Inspect the supplied features in the exact style you have, recording the numeral choice used in each line. Do not infer alignment or numeral height from a menu label alone. Keep a default line alongside the feature-enabled line so a collaborator can see what changed. The independent Bitter specimen below is a slab-serif comparison, not a Slam preview.
Your questions, answered.
Who designed Slam?
Slam is by Gert Wiescher, published by Wiescher Design.
Is Slam only a headline font?
Wiescher describes it as designed with body copy in mind. Its paragraph texture is therefore worth comparing alongside its display appearance.
