This is how a comfortable mowing stance looks like.
The right hand could have been extended even more (to relax your biceps).
Here is how you can reliably discover snath size:
Hold some kind of stick (e.g. pencil) in your fist. Stay on a level floor, feet somewhat wider than shoulder width. Both shoulders are relaxed with arms freely hanging. Hold the stick level with the ground and have someone measure how high from the ground the stick is (the lower side of the stick). Measure perpendicular to the ground. This corresponds to the lower handle height while mowing.
In the table below, find the range (ranges) where your measurement fells. Pick the snath size that includes your measurement in its range. Note that these measurements work when using scythes from us. Other scythes have different tang angles and throw off these measurements.
(Example: With Markéta on the picture we measured 75 cm. Size S would fit her with grips adjusted to the max position. Size M would work in the middle position. Size L in the min position. To be safe, we would recommend snath M)
|Snath Size||Range of grip height - your measurement should fell into at least one of these|
|XS||46 - 56 cm|
|S||63 - 75 cm|
|M||69 - 80 cm|
75 - 87 cm
If your measurement reads above 87, it is still possible to mow with a straight back by holding the snath steeper to the ground. You will have to cut off a small wedge from the snath shaft to maintain a proper lay angle of the scythe.
