Neil Armstrong signature
Very tall thin strokes rise above the compact connected name.
What does Neil Armstrong’s signature look like?
Very tall thin strokes rise above the compact connected name. A long horizontal oval passes beneath it, crossing the lower parts of the larger uprights and continuing to the right. Compare the tall upper loop with that shallow lower return: their contrasting directions give the specimen a narrow but strongly layered silhouette.

About Neil Armstrong and this autograph
Neil Armstrong (5 August 1930 – 25 August 2012) was an American astronaut and lunar explorer. This specimen is the Wikimedia Commons vector rendering of Neil Armstrong’s signature.
Neil Armstrong signature and handwriting analysis
Neil Armstrong’s signature sample has an almost upright slant, a rising baseline and 5 enclosed loops. Comparing autograph strokes, baseline angle (+3.9°), slant (−1°), opening ratio (0.10×) and enclosed loops (5) reveals how individual signature traits contrast with standard handwriting features. Use the layers to follow the writing line, letter band, slant and enclosed loops.

Opening, letter body and finish
The opening is lower than the typical letter body. The opening-to-body ratio is 0.10×, while the whole image is 0.93 times as wide as it is tall. The rightmost ink finishes above the writing line; look at this ending separately from the slant of the letters themselves.
Loops and the lower flourish
The sample contains 5 enclosed loops and 1 main ink group. The lower flourish spans about 74% of the full ink width, giving the name another line to follow beneath its letters.
All 11 measured signature features
Slant
−1°Angle of the letter strokes from vertical. Positive angles lean right; negative angles lean left.
The signature has a near-upright slant (−1°). The blue-green guides show the lean of strokes across the name.
Baseline
+3.9°Direction of the writing line from the beginning to the end of the signature.
The writing line rises (+3.9°). The red guide follows the base of the letters, separate from lower loops and flourishes.
Opening capital
0.1×Height of the opening letter relative to the typical letters that follow. 1× means similar heights.
The opening stands 0.1 times as high as the following letters. The purple box marks its area; the dashed blue guide marks the letter-body band.
Enclosed loops
5Closed spaces surrounded by ink, counted across the whole signature.
There are 5 enclosed loops in the sample. Orange outlines locate them. Compare their size and placement within the name.
Ink groups
1Separate connected areas of ink in the image. Dots or detached letters can form additional groups.
The signature contains 1 main ink group. Most of the visible ink joins into one connected shape. Look at where those shapes join or separate.
Ink density
4%Share of the signature’s enclosing rectangle occupied by ink.
Ink covers 4% of the measured signature area; the rest is open space. Compare the open areas with the thickness of the visible strokes.
Underline / flourish
74% wideLength of a lower underline or flourish compared with the full signature width.
A lower underline or flourish spans about 74% of the name’s width. Its highlighted area shows how much emphasis sits beneath the letters.
Finish height
+0.6×Height of the rightmost ending above or below the baseline, in typical letter heights. Positive is above; negative is below.
The ending sits close to the writing line (+0.6 letter heights). The orange guide locates the finish relative to the red baseline.
Width / height
0.9 : 1Full ink width divided by full ink height, including the signature’s tall and low strokes.
The shape is 0.9 times as wide as it is high. Its ink spans 278 × 299 image pixels. Compare the horizontal spread with the vertical reach of the capitals and loops.
Ornamentation
6.9×Total traced stroke length divided by signature width. More turns and retraced shapes add length.
The traced strokes total 1,930 pixels, about 6.9 times the signature’s width. Look for loops, turns and flourishes that add movement within that width.
Angularity
3.5Number of corners per 100 pixels of traced ink outline. Higher values indicate more frequent sharp turns.
The outline contains about 3.5 corners per 100 pixels. Inspect the turns in the pen-path layer and compare pointed changes of direction with rounded curves.
