Who You'd Reach

KasperCalc is used by aerospace and mechanical design engineers doing real design work: sizing springs, seals, and fasteners; pulling material allowables from MIL-HDBK-5; and working out fluid properties for fuel, hydraulic, and coolant systems. Visitors come here to solve a specific engineering problem, which makes this a focused, technical, professional audience — the kind of people who spec and buy the parts and materials they're calculating around.

What Makes KasperCalc Different

KasperCalc doesn't use Google Ads or any other ad network. Every ad is a direct partnership: you work with us, your ad runs on the pages you choose, and nothing is auctioned, resold, or swapped out by an algorithm.

Direct partnership No network, no auction, no middleman. You know exactly where your ad appears and who it's shown to.
Fast, crisp static images Ads are optimized images hosted on KasperCalc's own servers. They load with the page and stay sharp on high-resolution screens.
Seen, not blocked Because ads are served directly by KasperCalc rather than an ad network, most ad blockers won't hide them.
No tracking No scripts, pixels, or cookies in ads, and we don't track views or clicks of individual ads. Our readers' trust carries over to your brand.
Never in the way Ads sit beside the tools, never inside a calculator, and never as pop-ups, overlays, animation, or autoplaying media.
Brand-safe Every ad is reviewed before it goes live, so your brand appears only alongside professional engineering content and other vetted partners.
Placements & Ad Specs

On desktop, ads run in fixed rails beside the page content. On mobile and other narrow screens, where there's no room for a side rail, a single inline placement is used instead. Full details are in our Advertising Policy.

  • Desktop: sticky 160×600 rail placements, left and/or right of the content.
  • Mobile / narrow screens: one inline placement, sized to fit the page.
  • Format: a single static image (PNG, JPEG, WebP, or SVG) linking to the page of your choice.
  • For the sharpest result, supply artwork at twice the placement size (for example, 320×1200 for a 160×600 rail). We handle optimization.
  • Want to measure results? Add your own campaign tags (such as UTM parameters) to your destination link.
