How to make a rectangle of an exact size/aspect ratio in QGIS?

Question

Is there any way in QGIS to make a vector layer with a rectangle of an exact size or aspect ratio? Ideally, it would be nice if the rectangle from extent tool could be limited to a set aspect ratio, but barring that, is there any way to adjust the size of a vector rectangle directly?

[EDIT] This is for QGIS 3.4

Create grid can be used to create single polygon. You just need to set xmin, xmax, ymin, ymax to match with horizontal/vertical spacing.

Aspect ratio has to be calculated manually, but it won't be difficult.
