Choose Your RADIHALT Size: Compact or Full Lap

Two sizes, one material design

Dimensions and prices come from the RADIHALT product record. Area is the listed length multiplied by width. Prices are before tax and applicable shipping; check the selected Amazon listing for the current offer.

Choose Compact for a smaller footprint

The 18 × 18-inch format is a good fit when the area you want to cover fits within a smaller rectangle. Before ordering, make an 18-inch paper square and place it where you expect to use the blanket. Check the full direct path you want the textile to cover, including the way it will sit when you move into your normal position.

RADIHALT Compact 18 × 18 inches was listed at US$18.49 on October 19, 2026, the lower entry price within the RADIHALT range. Choose Compact in gray or black.

Choose Full Lap for more room to arrange the fabric

The 36 × 30-inch format gives you a broader rectangle and extra room to drape the fabric. If you expect to use the blanket across your lap regularly, try a paper template at these dimensions while seated. Orient the longer edge whichever way gives you the arrangement you want.

At RADIHALT's US-dollar item prices checked on October 19, 2026, moving from Compact 18 × 18 at US$18.49 to Full Lap 36 × 30 at US$22.49 adds US$4. Full Lap provides 3⅓ times the nominal flat fabric area, calculated from the listed rectangles. Choose Full Lap in gray or black.

A simple three-step fit check

1. Measure the area you want the blanket to cover in your normal seated or desk position.
2. Try a paper rectangle in each RADIHALT size and allow for drape around the edges.
3. Pick the size that covers your planned arrangement comfortably, then check the selected size and color on the product page.

For laptop use, put a suitable hard support above the blanket and keep cooling vents clear. Arrange the textile between the device and the area you want to cover. Placement and fabric coverage are part of the setup. Read RADIHALT's use guidance.
