1320w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"text-justify\">In the traditional system, you determine this height as a percentage of the head circumference. However, this method assumes that all heads with the same circumference share similar volumetric proportions, which is not always true, especially in structured sizes.<\/p>\n\n\n\n<p class=\"text-justify\">To achieve a more stable shape and avoid ogive deformation or excessively low crowns, you can relate the height of the curved portion of the crown to the equivalent cranial diameter.<\/p>\n\n\n\n<p class=\"text-justify\">Define the equivalent diameter as:<\/p>\n\n\n\n<div class=\"wp-block-math\"><math display=\"block\"><semantics><mrow><msub><mi>d<\/mi><mrow><mi>e<\/mi><mi>q<\/mi><\/mrow><\/msub><mo>=<\/mo><mfrac><mrow><mi>L<\/mi><mo>+<\/mo><mi>W<\/mi><\/mrow><mn>2<\/mn><\/mfrac><\/mrow><annotation encoding=\"application\/x-tex\">d_{eq} = \\frac{L + W}{2}<\/annotation><\/semantics><\/math><\/div>\n\n\n\n<p class=\"text-justify\">where <strong>L<\/strong> represents the anteroposterior diameter and <strong>W<\/strong> the bilateral diameter.<\/p>\n\n\n\n<p class=\"text-justify\">Establish the dome height as a constant proportion of this diameter:<\/p>\n\n\n\n<div class=\"wp-block-math\"><math display=\"block\"><semantics><mrow><msub><mi>h<\/mi><mi>c<\/mi><\/msub><mo>=<\/mo><mn>0,70<\/mn><mo>\u22c5<\/mo><msub><mi>d<\/mi><mrow><mi>e<\/mi><mi>q<\/mi><\/mrow><\/msub><\/mrow><annotation encoding=\"application\/x-tex\">h_c = 0,70 \\cdot d_{eq}<\/annotation><\/semantics><\/math><\/div>\n\n\n\n<p class=\"text-justify\">The coefficient 0.70 provides a balanced dome, close to the equivalent spherical geometry of the skull, and prevents both the \u201cflat crown\u201d effect and the ogival tendency in structured models.<\/p>\n\n\n\n<p class=\"text-justify\">Do not obtain the variation between low, medium, or high models by modifying this proportion; instead, adjust the lower structural segment of the panel.<\/p>\n\n\n\n<p class=\"text-justify\">In this way, express the total crown height as:<\/p>\n\n\n\n<div class=\"wp-block-math\"><math display=\"block\"><semantics><mrow><msub><mi>H<\/mi><mtext>total<\/mtext><\/msub><mo>=<\/mo><msub><mi>H<\/mi><mtext>crown<\/mtext><\/msub><mo>+<\/mo><msub><mi>H<\/mi><mtext>base<\/mtext><\/msub><\/mrow><annotation encoding=\"application\/x-tex\">H_{\\text{total}} = H_{\\text{crown}} + H_{\\text{base}}<\/annotation><\/semantics><\/math><\/div>\n\n\n\n<p class=\"text-justify\">where <strong>H_base<\/strong> represents the height added in the lower section of the panel.<\/p>\n\n\n\n<p class=\"text-justify\">This approach allows you to maintain a harmonious and stable dome across all sizes, varying only the visual proportion of the whole without altering the upper geometry.<\/p>\n\n\n\n<p class=\"text-justify\">The total crown height determines the visual character of the cap.<\/p>\n\n\n\n<p class=\"text-justify\">You can construct the same size with a lower, intermediate, or higher placement by modifying the vertical proportion of the whole without changing the support circumference.<\/p>\n\n\n\n<p class=\"text-justify\">This variation lets you adapt the model to different styles, from discreet configurations close to the skull to more structured versions with greater presence.<\/p>\n\n\n\n<p class=\"text-justify\">In the system described, do not achieve this difference by modifying the curvature of the dome; instead, adjust the height of the lower

class=\"text-justify\">A baseball cap may be constructed with 5, 6, 7 or 8 gores.<\/p>\n\n\n\n<p class=\"text-justify\">The number of gores or panels does not change the circumference or the dome height; it only changes how the cap surface gets subdivided.<\/p>\n\n\n\n<p class=\"text-justify\">The most common configuration is the 6-gore model, which constitutes the classic and most widespread version.<\/p>\n\n\n\n<p class=\"text-justify\">Caps with 7 or 8 gores are closer to the field of hat-making, as they allow a finer subdivision of the crown surface and a distinct formal character.<\/p>\n\n\n\n<p class=\"text-justify\">5- and 6-gore caps may incorporate a rear adjuster for size regulation. In this case, the two rear pieces are presented open, excavating a section of the back edge of the crown to accommodate the adjustment system.<\/p>\n\n\n\n<p class=\"text-justify\">The use of an adjuster is especially frequent in 5-gore caps. The adjuster may function through different systems, the most common being: strap, buckle or metal adjuster, Velcro or snapback.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter

However, its importance is not purely functional: it is the element that projects the cap forward visually and largely defines its aesthetic character.<\/p>\n\n\n\n<p class=\"text-justify\">From a construction standpoint, draft the brim flat and then shape it into curvature. Do not design it arbitrarily; relate it directly to the head circumference (<strong>k<\/strong>) on which you build the crown.<\/p>\n\n\n\n<p class=\"text-justify\">In our system, develop the brim through a proportional and scalable method. This approach allows you to generate any size \u2014 from baby to adult \u2014 while maintaining the geometric coherence of the whole.<\/p>\n\n\n\n<p class=\"text-justify\">The brim depends on three main parameters:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li class=\"text-justify\"><strong>Width<\/strong>, determined by the opening angle.<\/li>\n\n\n\n<li><strong>Length<\/strong>, which defines the frontal projection.<\/li>\n\n\n\n<li><strong>Rounding<\/strong>, which softens the tips and the transition between the sides and the front section.<\/li>\n<\/ol>\n\n\n\n<p class=\"text-justify\">These three parameters allow you to control both the proportion and the visual behavior of the piece precisely, avoiding deformation or improvised solutions. In the following sections, we will develop each of them independently.<\/p>\n\n\n\n<h3 class=\"wp-block-heading text-justify has-medium-font-size\"><strong>Brim Width<\/strong><\/h3>\n\n\n\n<p class=\"text-justify\">The brim width determines how much the front section \u201cembraces\u201d the head. This parameter defines its lateral opening and therefore its visual presence within the overall cap.<\/p>\n\n\n\n<p class=\"text-justify\">Unlike the length \u2014 which projects the piece forward \u2014 the width controls its extension along the front perimeter of the skull. A wider brim creates a more enveloping and sporty image; a narrower one produces a lighter and more restrained effect.<\/p>\n\n\n\n<p class=\"text-justify\">From a geometric standpoint, define the width through a central angle drawn on the head circumference (<strong>k<\/strong>). This angle determines the base arc on which you construct the piece and, consequently, its lateral opening.<\/p>\n\n\n\n<p class=\"text-justify\">The larger the angle, the greater the frontal arc the brim occupies along the head perimeter and the more enveloping its appearance becomes. The smaller the angle, the more restrained and lighter the lateral projection will appear.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-1024x576.jpg\" alt=\"Geometric definition of visor width using a central angle on head circumference (k)\" class=\"wp-image-6196\" srcset=\"https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-1024x576.jpg 1024w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-300x169.jpg 300w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-768x432.jpg 768w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-1536x864.jpg 1536w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-2048x1152.jpg 2048w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_06-1320x743.jpg 1320w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p>In our system, define three proportional variants:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>120\u00b0 \u2192 narrow brim<\/strong><\/li>\n\n\n\n<li><strong>140\u00b0 \u2192 medium brim<\/strong><\/li>\n\n\n\n<li><strong>160\u00b0 \u2192 wide brim<\/strong><\/li>\n<\/ul>\n\n\n\n<p>These three options allow you to modulate the character of the cap without altering its geometric coherence, since you always calculate the angle in direct relation to the head circumference.

However, the brim width does not depend on the number of panels; it depends solely on the arc defined on the head circumference.<\/p>\n\n\n\n<p class=\"text-justify\">In the next section, we define the second fundamental parameter: the brim length.<\/p>\n\n\n\n<h2 class=\"wp-block-heading text-justify has-medium-font-size\"><strong>Brim Length<\/strong><\/h2>\n\n\n\n<p class=\"text-justify\">The brim length determines its frontal projection, that is, the distance the piece extends forward from the head circumference.<\/p>\n\n\n\n<p class=\"text-justify\">While you define the width through an angle along the perimeter, construct the length in direct relation to the <strong>radius (r)<\/strong> of the base circle.<\/p>\n\n\n\n<p class=\"text-justify\">Recall that you obtain this radius from the head circumference (<strong>k<\/strong>) through the relation:<\/p>\n\n\n\n<div class=\"wp-block-math\"><math display=\"block\"><semantics><mrow><mi>r<\/mi><mo>=<\/mo><mfrac><mi>k<\/mi><mrow><mn>2<\/mn><mi>\u03c0<\/mi><mi>r<\/mi><\/mrow><\/mfrac><\/mrow><annotation encoding=\"application\/x-tex\">r = \\frac{k}{2\\pi r}<\/annotation><\/semantics><\/math><\/div>\n\n\n\n<p class=\"text-justify\">In this way, each size automatically generates its corresponding radius, ensuring the proportional coherence of the system.<\/p>\n\n\n\n<p class=\"text-justify\">Instead of expressing the length as a fixed measurement in centimeters, define it as a fraction of the radius. Establish three variants:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-1024x576.jpg\" alt=\"Relationship between head radius (r), visor angle, and proportional length (0.62r, 0.75r, 0.87r)\" class=\"wp-image-6216\" srcset=\"https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-1024x576.jpg 1024w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-300x169.jpg 300w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-768x432.jpg 768w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-1536x864.jpg 1536w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-2048x1152.jpg 2048w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/bcp-9_08-1320x743.jpg 1320w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<ul class=\"wp-block-list\">\n<li class=\"text-justify\"><strong>0,87 r \u2192 long brim<\/strong><\/li>\n\n\n\n<li class=\"text-justify\"><strong>0,75 r \u2192 medium<\/strong> <strong>brim<\/strong><\/li>\n\n\n\n<li class=\"text-justify\"><strong>0,62 r \u2192&nbsp;short<\/strong> <strong>brim<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"text-justify\">These proportions allow you to modulate the frontal presence of the cap without breaking its geometric balance. Since the length depends on the radius, it scales automatically with any head circumference.<\/p>\n\n\n\n<p class=\"text-justify\">The numerical difference between these three options may seem small, but it produces clearly perceptible visual variations in the final result. Increasing the fraction of the radius enhances projection and gives the piece greater presence; reducing it creates a more restrained and lighter brim.<\/p>\n\n\n\n<p class=\"text-justify\">Measure the length along the central front axis, from the base arc defined by the angle to the front edge of the brim. In the next section, we address the third fundamental parameter: brim rounding, which regulates the transition between the front and the sides.<\/p>\n\n\n\n<h2 class=\"wp-block-heading text-justify has-medium-font-size\"><strong>Brim Rounding<\/strong><\/h2>\n\n\n\n<p class=\"text-justify\">Rounding regulates the transition between the front and the sides of the brim. It does not modify either the angle or the length, but it determines how smoothly they meet.<\/p>\n\n\n\n<p class=\"text-justify\">In the previous illustrations, the brims already appear rounded. This allows you to observe how the form evolves when you construct the rounding in coherence with the frontal projection.<\/p>\n\n\n\n<p class=\"text-justify\">In our system, do not draw the rounding arbitrarily. Obtain it by using the brim projection itself as an auxiliary radius.<\/p>\n\n\n\n<p class=\"text-justify\">In other words, use the length defined as a fraction of <strong>r<\/strong> (0.62 r, 0.75 r, or 0.87 r) as the radius of the circle that generates the transition arc at the tips.<\/p>\n\n\n\n<p class=\"text-justify\">Thus:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"text-justify\">A short brim produces a more restrained rounding.<\/li>\n\n\n\n<li class=\"text-justify\">A medium brim creates a balanced transition.<\/li>\n\n\n\n<li class=\"text-justify\">A long brim offers a broader and more enveloping curve.<\/li>\n<\/ul>\n\n\n\n<p class=\"text-justify\">The result is a fully proportional system in which the rounding scales automatically together with the length and maintains coherence at any size.<\/p>\n\n\n\n<p class=\"text-justify\">This procedure prevents breaks, forced tangencies, or rigid terminations, ensuring geometric continuity along the perimeter of the piece.<\/p>\n\n\n\n<h2 class=\"wp-block-heading text-justify has-medium-font-size\">Rear Adjustment of the Cap<\/h2>\n\n\n\n<p class=\"text-justify\">In adjustable caps, the rear opening allows you to adapt the circumference without altering the frontal geometry. Its construction must maintain proportional coherence both with the head circumference and with the panel structure. In our system, define the opening through two simple and constant rules<\/p>\n\n\n\n<p class=\"text-justify\">.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img

starting, note that you can find all the values required for this drafting (circumference, theoretical radius, angle \u03b2, lengths, and proportions) in the table in the following section.<\/p>\n\n\n\n<p class=\"text-justify\">In this section, we focus exclusively on the geometric procedure.<\/p>\n\n\n\n<p class=\"text-justify\">Start from a point that will act as the construction center.<\/p>\n\n\n\n<p class=\"text-justify\">From this point, draw vertically the theoretical head radius (<strong>rt<\/strong>), which forms the axis of symmetry of the system.<\/p>\n\n\n\n<p class=\"text-justify\">At the upper end of this axis, construct the total brim angle (<strong>\u03b2<\/strong>), dividing it into two equal parts:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"text-justify\">\u03b2\/2 to one side<\/li>\n\n\n\n<li class=\"text-justify\">\u03b2\/2 to the other side<\/li>\n<\/ul>\n\n\n\n<p class=\"text-justify\">These two directions define the frontal opening of the brim.<\/p>\n\n\n\n<p class=\"text-justify\">Next, from the same upper point, draw an arc connecting the three resulting lines (the vertical axis and the two lateral directions).<\/p>\n\n\n\n<p class=\"text-justify\">This arc \u2014 shown in magenta in the illustration \u2014 corresponds to the junction line between the brim and the crown of the cap.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\"

class=\"text-justify\">At the point where <strong>rt<\/strong> ends and <strong>lv<\/strong> begins, draw a line perpendicular to the vertical axis.<\/p>\n\n\n\n<p class=\"text-justify\">From the lower end of the brim length, draw a line parallel to the previous one.<\/p>\n\n\n\n<p class=\"text-justify\">Finally, draw two lines parallel to the theoretical radius axis (<strong>rt<\/strong>) passing through the start and end points of the arc that connects to the crown. These operations define the \u201cstructural rectangle\u201d within which the brim will be developed.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-1024x576.jpg\" alt=\"Brim structural rectangle defined by lines parallel to the theoretical radius axis rt\" class=\"wp-image-6245\" srcset=\"https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-1024x576.jpg 1024w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-300x169.jpg 300w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-768x432.jpg 768w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-1536x864.jpg 1536w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-2048x1152.jpg 2048w, https:\/\/tevipa.com\/blog\/wp-content\/uploads\/2026\/02\/v_03-1320x743.jpg 1320w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"text-justify\">From the two lower corners of the structural rectangle, measure inward toward the center the brim length (<strong>lv<\/strong>).<\/p>\n\n\n\n<p class=\"text-justify\">Through the points obtained, draw perpendicular lines upward from the lower line until they intersect the upper parallel line.<\/p>\n\n\n\n<p class=\"text-justify\">The resulting intersection points form the centers of the rounding arcs of the brim.
